From 5b615287b37c32dc0c9dbeab13b19ac87828a5f7 Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Tue, 16 Oct 2007 18:38:25 -0400 Subject: [PATCH] ext4: fix setup_new_group_blocks locking 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.
