From 955ce5f5be67dfe0d1d096b543af33fe8a1ce3dd Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Sat, 2 May 2009 20:35:09 -0400 Subject: ext4: Convert ext4_lock_group to use sb_bgl_lock We have sb_bgl_lock() and ext4_group_info.bb_state bit spinlock to protech group information. The later is only used within mballoc code. Consolidate them to use sb_bgl_lock(). This makes the mballoc.c code much simpler and also avoid confusion with two locks protecting same info.
