OGAWA Hirofumi 9aacd59934 fat: gcc 4.3 warning fix
This patch fixes the following warnings.

fs/fat/dir.c: In function 'fat_parse_long':
include/linux/msdos_fs.h:294: warning: array subscript is above array bounds
include/linux/msdos_fs.h:295: warning: array subscript is above array bounds
include/linux/msdos_fs.h:295: warning: array subscript is above array bounds

The ->name is defined as "name[8], ext[3]", but fat_checksum() uses
those as name[11]. There is no actual problem, but it's not a good manner.

OGAWA Hirofumi 28ec039c21 fat: don't use free_clusters for fat32
It seems that the recent Windows changed specification, and it's
undocumented.  Windows doesn't update ->free_clusters correctly.

This patch doesn't use ->free_clusters by default.  (instead, add "usefree"
for forcing to use it)

Arjan van de Ven c5ef1c42c5 [PATCH] mark struct inode_operations const 3
Many struct inode_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

OGAWA Hirofumi da63fc7ce6 [PATCH] fat: add fat_getattr()
This adds fat_getattr() for setting stat->blksize. (FAT uses the size
of cluster for proper I/O)

Chris Mason ae78bf9c4f [PATCH] add -o flush for fat
Fat is commonly used on removable media.  Mounting with -o flush tells the
FS to write things to disk as quickly as possible.  It is like -o sync, but
much faster (and not as safe).

Arjan van de Ven 4b6f5d20b0 [PATCH] Make most file operations structs in fs/ const
This is a conversion to make the various file_operations structs in fs/
const.  Basically a regexp job, with a few manual fixups

The goal is both to increase correctness (harder to accidentally write to
shared datastructures) and reducing the false sharing of cachelines with
things that get dirty in .data (while .rodata is nicely read only and thus
cache clean)

Arjan van de Ven 6b9438e132 [PATCH] fat_lock is used as a mutex, convert it to using the new mutex primitive
The fat code uses the fat_lock always in a mutex way (taking and releasing
the lock in the same function), the patch below converts it into the new
mutex primitive.  Please consider this patch for the code.

OGAWA Hirofumi e5174baaea [PATCH] fat: support ->direct_IO()
This patch add to support of ->direct_IO() for mostly read.

The user of this seems to want to use for streaming read.  So, current direct
I/O has limitation, it can only overwrite.  (For write operation, mainly we
need to handle the hole etc..)

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!
