Kees Cook ab62ef82ea ntfs: mft: remove VLA usage
In the quest to remove all stack VLA usage from the kernel[1], this
allocates the maximum size stack buffer.  Existing checks already
require that blocksize >= NTFS_BLOCK_SIZE and mft_record_size <=
PAGE_SIZE, so max_bhs can be at most PAGE_SIZE / NTFS_BLOCK_SIZE.
Sanity checks are added for robustness.

Christoph Hellwig 2c2acd2d19 ntfs: fix bogus __mark_inode_dirty(I_DIRTY_SYNC | I_DIRTY_DATASYNC) call
I_DIRTY_DATASYNC is a strict superset of I_DIRTY_SYNC semantics, as
in mark dirty to be written out by fdatasync as well.  So dirtying
for both flags makes no sense.

Jeff Layton 7a11ac289c ntfs: remove i_version handling
NTFS keeps track of the i_version counter here, seemingly for no reason.
It does not set the SB_I_VERSION flag so it'll never be incremented on
write, and it doesn't increment it internally for metadata operations.

Jens Axboe 640ab98fb3 buffer: have alloc_page_buffers() use __GFP_NOFAIL
Instead of adding weird retry logic in that function, utilize
__GFP_NOFAIL to ensure that the vm takes care of handling any
potential retries appropriately. This means we don't have to
call free_more_memory() from here.

Christoph Hellwig be297968da mm: only include blk_types in swap.h if CONFIG_SWAP is enabled
It's only needed for the CONFIG_SWAP-only use of bio_end_io_t.

Because CONFIG_SWAP implies CONFIG_BLOCK this will allow to drop some
ifdefs in blk_types.h.

Instead we'll need to add a few explicit includes that were implicit
before, though.

Deepa Dinamani c2050a454c fs: Replace current_fs_time() with current_time()
current_fs_time() uses struct super_block* as an argument.
As per Linus's suggestion, this is changed to take struct
inode* as a parameter instead. This is because the function
is primarily meant for vfs inode timestamps.
Also the function was renamed as per Arnd's suggestion.

Change all calls to current_fs_time() to use the new
current_time() function instead. current_fs_time() will be
deleted.

Kirill A. Shutemov 09cbfeaf1a mm, fs: get rid of PAGE_CACHE_* and page_cache_{get,release} macros
PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} macros were introduced *long* time
ago with promise that one day it will be possible to implement page
cache with bigger chunks than PAGE_SIZE.

This promise never materialized.  And unlikely will.

We have many places where PAGE_CACHE_SIZE assumed to be equal to
PAGE_SIZE.  And it's constant source of confusion on whether
PAGE_CACHE_* or PAGE_* constant should be used in a particular case,
especially on the border between fs and mm.

Global switching to PAGE_CACHE_SIZE != PAGE_SIZE would cause to much
breakage to be doable.

Let's stop pretending that pages in page cache are special.  They are
not.

The changes are pretty straight-forward:

 - <foo> << (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>;

 - <foo> >> (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>;

 - PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} -> PAGE_{SIZE,SHIFT,MASK,ALIGN};

 - page_cache_get() -> get_page();

 - page_cache_release() -> put_page();

This patch contains automated changes generated with coccinelle using
script below.  For some reason, coccinelle doesn't patch header files.
I've called spatch for them manually.

The only adjustment after coccinelle is revert of changes to
PAGE_CAHCE_ALIGN definition: we are going to drop it later.

There are few places in the code where coccinelle didn't reach.  I'll
fix them manually in a separate patch.  Comments and documentation also
will be addressed with the separate patch.

Anton Altaparmakov af5eb745ef NTFS: Fix invalid pointer dereference in ntfs_mft_record_alloc().
In ntfs_mft_record_alloc() when mapping the new extent mft record with
map_extent_mft_record() we overwrite @m with the return value and on
error, we then try to use the old @m but that is no longer there as @m
now contains an error code instead so we crash when dereferencing the
error code as if it were a pointer.

The simple fix is to use a temporary variable to store the return value
thus preserving the original @m for later use.  This is a backport from
the commercial Tuxera-NTFS driver and is well tested...

Thanks go to Julia Lawall for pointing this out (whilst I had fixed it
in the commercial driver I had failed to fix it in the Linux kernel).

Tejun Heo 5a0e3ad6af include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

This eliminates the i_blksize field from struct inode.  Filesystems that want
to provide a per-inode st_blksize can do so by providing their own getattr
routine instead of using the generic_fillattr() function.

Anton Altaparmakov ba6d2377c8 NTFS: Fix a nasty deadlock that appeared in recent kernels.
The situation: VFS inode X on a mounted ntfs volume is dirty.  For
      same inode X, the ntfs_inode is dirty and thus corresponding on-disk
      inode, i.e. mft record, which is in a dirty PAGE_CACHE_PAGE belonging
      to the table of inodes, i.e. $MFT, inode 0.
      What happens:
      Process 1: sys_sync()/umount()/whatever...  calls
      __sync_single_inode() for $MFT -> do_writepages() -> write_page for
      the dirty page containing the on-disk inode X, the page is now locked
      -> ntfs_write_mst_block() which clears PageUptodate() on the page to
      prevent anyone else getting hold of it whilst it does the write out.
      This is necessary as the on-disk inode needs "fixups" applied before
      the write to disk which are removed again after the write and
      PageUptodate is then set again.  It then analyses the page looking
      for dirty on-disk inodes and when it finds one it calls
      ntfs_may_write_mft_record() to see if it is safe to write this
      on-disk inode.  This then calls ilookup5() to check if the
      corresponding VFS inode is in icache().  This in turn calls ifind()
      which waits on the inode lock via wait_on_inode whilst holding the
      global inode_lock.
      Process 2: pdflush results in a call to __sync_single_inode for the
      same VFS inode X on the ntfs volume.  This locks the inode (I_LOCK)
      then calls write-inode -> ntfs_write_inode -> map_mft_record() ->
      read_cache_page() for the page (in page cache of table of inodes
      $MFT, inode 0) containing the on-disk inode.  This page has
      PageUptodate() clear because of Process 1 (see above) so
      read_cache_page() blocks when it tries to take the page lock for the
      page so it can call ntfs_read_page().
      Thus Process 1 is holding the page lock on the page containing the
      on-disk inode X and it is waiting on the inode X to be unlocked in
      ifind() so it can write the page out and then unlock the page.
      And Process 2 is holding the inode lock on inode X and is waiting for
      the page to be unlocked so it can call ntfs_readpage() or discover
      that Process 1 set PageUptodate() again and use the page.
      Thus we have a deadlock due to ifind() waiting on the inode lock.
      The solution: The fix is to use the newly introduced
      ilookup5_nowait() which does not wait on the inode's lock and hence
      avoids the deadlock.  This is safe as we do not care about the VFS
      inode and only use the fact that it is in the VFS inode cache and the
      fact that the vfs and ntfs inodes are one struct in memory to find
      the ntfs inode in memory if present.  Also, the ntfs inode has its
      own locking so it does not matter if the vfs inode is locked.

Anton Altaparmakov b6ad6c52fe NTFS: - Split ntfs_map_runlist() into ntfs_map_runlist() and a non-locking
helper ntfs_map_runlist_nolock() which is used by ntfs_map_runlist().
	This allows us to map runlist fragments with the runlist lock already
	held without having to drop and reacquire it around the call.  Adapt
	all callers.
      - Change ntfs_find_vcn() to ntfs_find_vcn_nolock() which takes a locked
	runlist.  This allows us to find runlist elements with the runlist
	lock already held without having to drop and reacquire it around the
	call.  Adapt all callers.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
