Dave Kleikamp 833f73299f [PATCH] EXT2: Remove superblock lock contention in ext2_statfs ... Fix a performance degradation introduced in 2.6.17. (30% degradation running dbench with 16 threads) Commit 21730eed11, 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 5b11687924) Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>		2006-09-19 07:59:59 -07:00
