Date: Wed, 17 Oct 2007 16:07:29 -0700 From: akpm@...ux-foundation.org To: mm-commits@...r.kernel.org Cc: sandeen@...hat.com, linux-ext4@...r.kernel.org Subject: + ext3-fix-setup_new_group_blocks-locking.patch added to -mm tree The patch titled ext3: fix setup_new_group_blocks locking has been added to the -mm tree. Its filename is ext3-fix-setup_new_group_blocks-locking.patch *** Remember to use Documentation/SubmitChecklist when testing your code *** See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find out what to do about this ------------------------------------------------------ Subject: ext3: fix setup_new_group_blocks locking From: Eric Sandeen <sandeen@...hat.com> setup_new_group_blocks() manipulates the group descriptor block bh under the block_bitmap bh's lock. It shouldn't matter since nobody but resize should be touching these blocks, but it's worth fixing up.
