Theodore Ts'o ba52de123d [PATCH] inode-diet: Eliminate i_blksize from the inode structure
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.

Note that some filesystems were providing pretty much random (and incorrect)
values for i_blksize.

Eric Sandeen eee194e76c [PATCH] ext3: inode numbers are unsigned long
This is primarily format string fixes, with changes to ialloc.c where large
inode counts could overflow, and also pass around journal_inum as an
unsigned long, just to be pedantic about it....

Mingming Cao 1c2bf374a4 [PATCH] ext3_fsblk_t: filesystem, group blocks and bug fixes
Some of the in-kernel ext3 block variable type are treated as signed 4 bytes
int type, thus limited ext3 filesystem to 8TB (4kblock size based).  While
trying to fix them, it seems quite confusing in the ext3 code where some
blocks are filesystem-wide blocks, some are group relative offsets that need
to be signed value (as -1 has special meaning).  So it seem saner to define
two types of physical blocks: one is filesystem wide blocks, another is
group-relative blocks.  The following patches clarify these two types of
blocks in the ext3 code, and fix the type bugs which limit current 32 bit ext3
filesystem limit to 8TB.

With this series of patches and the percpu counter data type changes in the mm
tree, we are able to extend exts filesystem limit to 16TB.

This work is also a pre-request for the recent >32 bit ext3 work, and makes
the kernel to able to address 48 bit ext3 block a lot easier: Simply redefine
ext3_fsblk_t from unsigned long to sector_t and redefine the format string for
ext3 filesystem block corresponding.

Two RFC with a series patches have been posted to ext2-devel list and have
been reviewed and discussed:
http://marc.theaimsgroup.com/?l=ext2-devel&m=114722190816690&w=2

http://marc.theaimsgroup.com/?l=ext2-devel&m=114784919525942&w=2

Patches are tested on both 32 bit machine and 64 bit machine, <8TB ext3 and
>8TB ext3 filesystem(with the latest to be released e2fsprogs-1.39).  Tests
includes overnight fsx, tiobench, dbench and fsstress.

This patch:

Defines ext3_fsblk_t and ext3_grpblk_t, and the printk format string for
filesystem wide blocks.

This patch classifies all block group relative blocks, and ext3_fsblk_t blocks
occurs in the same function where used to be confusing before.  Also include
kernel bug fixes for filesystem wide in-kernel block variables.  There are
some fileystem wide blocks are treated as int/unsigned int type in the kernel
currently, especially in ext3 block allocation and reservation code.  This
patch fixed those bugs by converting those variables to ext3_fsblk_t(unsigned
long) type.

- having prototypes for ext3_count_free() in two different headers is

Glauber de Oliveira Costa 5b11687924 [PATCH] Locking problems while EXT3FS_DEBUG on
I noticed some problems while running ext3 with the debug flag set on.
More precisely, I was unable to umount the filesystem.  Some investigation
took me to the patch that follows.

At a first glance , the lock/unlock I've taken out seems really not
necessary, as the main code (outside debug) does not lock the super.  The
only additional danger operations that debug code introduces seems to be
related to bitmap, but bitmap operations tends to be all atomic anyway.

I also took the opportunity to fix 2 spelling errors.

Stephen Smalley ac50960afa [PATCH] ext3: Enable atomic inode security labeling
This patch modifies ext3 to call the inode_init_security LSM hook to obtain
the security attribute for a newly created inode and to set the resulting
attribute on the new inode as part of the same transaction.  This parallels
the existing processing for setting ACLs on newly created inodes.

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!
