Al Viro ea022dfb3c ocfs: simplify symlink handling
seeing that "fast" symlinks still get allocation + copy, we might as
well simply switch them to pagecache-based variant of ->follow_link();
just need an appropriate ->readpage() for them...

David Teigland 60f98d1839 dlm: add recovery callbacks
These new callbacks notify the dlm user about lock recovery.
GFS2, and possibly others, need to be aware of when the dlm
will be doing lock recovery for a failed lockspace member.

In the past, this coordination has been done between dlm and
file system daemons in userspace, which then direct their
kernel counterparts.  These callbacks allow the same
coordination directly, and more simply.

Akinobu Mita 939255798a ocfs2: avoid unaligned access to dqc_bitmap
The dqc_bitmap field of struct ocfs2_local_disk_chunk is 32-bit aligned,
but not 64-bit aligned.  The dqc_bitmap is accessed by ocfs2_set_bit(),
ocfs2_clear_bit(), ocfs2_test_bit(), or ocfs2_find_next_zero_bit().  These
are wrapper macros for ext2_*_bit() which need to take an unsigned long
aligned address (though some architectures are able to handle unaligned
address correctly)

So some 64bit architectures may not be able to access the dqc_bitmap
correctly.

This avoids such unaligned access by using another wrapper functions for
ext2_*_bit().  The code is taken from fs/ext4/mballoc.c which also need to
handle unaligned bitmap access.

Xiaowei.Hu 0393afea31 ocfs2: Add a missing journal credit in ocfs2_link_credits() -v2
With indexed_dir enabled, ocfs2 maintains a list of dirblocks having
space.

The credit calculation in ocfs2_link_credits() did not correctly account
for adding an entry that exactly fills a dirblock that triggers removing
that dirblock by changing the pointer in the previous block in the list.
The credit calculation did not account for that previous block.

To expose, do:

mkfs.ocfs2 -b 512 -M local /dev/sdX
mount /dev/sdX /ocfs2
mkdir /ocfs2/linkdir
touch /ocfs2/linkdir/file1
for i in `seq 1 29` ; do link /ocfs2/linkdir/file1
/ocfs2/linkdir/linklinklinklinklinklink$i; done
rm -f /ocfs2/linkdir/linklinklinklinklinklink10
sleep 8
link /ocfs2/linkdir/file1
/ocfs2/linkdir/linklinklinklinklinklinkaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

Note:
The link names have been crafted for a 512 byte blocksize. Reproducing
with a larger blocksize will require longer (or more) links. The sleep
is important. We want jbd2 to commit the transaction so that the missing
block does not piggy back on account of the previous transaction.

Wengang Wang 8298524803 ocfs2: make direntry invalid when deleting it
When we deleting a direntry from a directory, if it's the first in a block we
invalid it by setting inode to 0; otherwise, we merge the deleted one to the
prior and contiguous direntry. And we don't truncate directories.

There is a problem for the later case since inode is not set to 0.
This problem happens when the caller passes a file position as parameter to
ocfs2_dir_foreach_blk(). If the position happens to point to a stale(not
the first, deleted in betweens of ocfs2_dir_foreach_blk()s) direntry, we are
not able to recognize its staleness. So that we treat it as a live one wrongly.

The fix is to set inode to 0 in both cases indicating the direntry is stale.
This won't introduce additional IOs.

Joe Perches b9075fa968 treewide: use __printf not __attribute__((format(printf,...)))
Standardize the style for compiler based printf format verification.
Standardized the location of __printf too.

Done via script and a little typing.

$ grep -rPl --include=*.[ch] -w "__attribute__" * | \
  grep -vP "^(tools|scripts|include/linux/compiler-gcc.h)" | \
  xargs perl -n -i -e 'local $/; while (<>) { s/\b__attribute__\s*\(\s*\(\s*format\s*\(\s*printf\s*,\s*(.+)\s*,\s*(.+)\s*\)\s*\)\s*\)/__printf($1, $2)/g ; print; }'

Paul Gortmaker afeacc8c1f fs: add export.h to files using EXPORT_SYMBOL/THIS_MODULE macros
These files were getting <linux/module.h> via an implicit include
path, but we want to crush those out of existence since they cost
time during compiles of processing thousands of lines of headers
for no reason.  Give them the lightweight header that just contains
the EXPORT_SYMBOL infrastructure.
