From 32ed5058ce90024efcd811254b4b1de0468099df Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Sat, 25 Apr 2009 22:53:39 -0400 Subject: ext4: Replace lock/unlock_super() with an explicit lock for resizing Use a separate lock to protect s_groups_count and the other block group descriptors which get changed via an on-line resize operation, so we can stop overloading the use of lock_super().
