[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] JFFS2: SUMMARY: fix a summary collecting bug

2006-09-16T19:54:32+00:00

In some special case (padding because of sync or umount) it can be possible
that summary information is not fit to the end of the erase block.  In
these cases the collecting of summary is disabled for this erase block.

The problem was that this was not respected by jffs2_sum_add_kvec().  This
patch fix this bug.

[PATCH] ext3 sequential read regression fix

2006-09-16T19:54:32+00:00

ext3-get-blocks support caused ~20% degrade in Sequential read
performance (tiobench). Problem is with marking the buffer boundary
so IO can be submitted right away. Here is the patch to fix it.

  2.6.18-rc6:
  -----------
  # ./iotest
  1048576+0 records in
  1048576+0 records out
  4294967296 bytes (4.3 GB) copied, 75.2726 seconds, 57.1 MB/s

  real    1m15.285s
  user    0m0.276s
  sys     0m3.884s

  2.6.18-rc6 + fix:
  -----------------
  [root@elm3a241 ~]# ./iotest
  1048576+0 records in
  1048576+0 records out
  4294967296 bytes (4.3 GB) copied, 62.9356 seconds, 68.2 MB/s

The boundary block check in ext3_get_blocks_handle needs to be adjusted
against the count of blocks mapped in this call, now that it can map
more than one block.

[PATCH] knfsd: Make ext3 reject filehandles referring to invalid inode number

2006-09-16T19:54:31+00:00

Inodes earlier than the 'first' inode (e.g.  journal, resize) should be
rejected early - except the root inode.  Also inode numbers that are too
big should be rejected early.

[PATCH] knfsd: Have ext2 reject file handles with bad inode numbers early

2006-09-16T19:54:30+00:00

This prevents bad inode numbers from triggering errors in ext2_get_inode.
