From 42a2b6ad71b011144d21d88a124140bb2bf1023f Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Thu, 18 Oct 2007 03:06:57 -0700 Subject: [PATCH] ext3: 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.
