remove unused bh in calls to ext234_get_group_desc

2007-10-17T15:42:49+00:00

ext[234]_get_group_desc never tests the bh argument, and only sets it if it
is passed in; it is perfectly happy with a NULL bh argument.  But, many
callers send one in and never use it.  May as well call with NULL like
other callers who don't use the bh.

[PATCH] inode-diet: Eliminate i_blksize from the inode structure

2006-09-27T15:26:18+00:00

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.

[PATCH] EXT2: Remove superblock lock contention in ext2_statfs

2006-09-19T14:59:59+00:00

Fix a performance degradation introduced in 2.6.17.  (30% degradation
running dbench with 16 threads)

Commit 21730eed11de42f22afcbd43f450a1872a0b5ea1, which claims to make
EXT2_DEBUG work again, moves the taking of the kernel lock out of
debug-only code in ext2_count_free_inodes and ext2_count_free_blocks and
into ext2_statfs.

The same problem was fixed in ext3 by removing the lock completely (commit
5b11687924e40790deb0d5f959247ade82196665)

[PATCH] Make EXT2_DEBUG work again

2006-06-25T17:01:12+00:00

This patch makes EXT2_DEBUG work again.  Due to lack of proper include
file, EXT2_DEBUG was undefined in bitmap.c and ext2_count_free() is left
out.  Moved to balloc.c and removed bitmap.c entirely.

Second, debug versions of ext2_count_free_{inodes/blocks} reacquires
superblock lock.  Moved lock into callers.

[PATCH] quota: fix error code for ext2_new_inode()

2006-02-03T16:32:09+00:00

The quota check in ext2_new_inode() returns ENOSPC where it should return
EDQUOT instead.
