ext4: fix a race which could leak memory in ext4_groupinfo_create_slab() In ext4_groupinfo_create_slab, we create ext4_groupinfo_caches within ext4_grpinfo_slab_create_mutex, but set it outside the lock, and there does exist some case that we may create it twice and causes a memory leak. So set it before we call mutex_unlock. Signed-off-by: Tao Ma <boyu.mt@taobao.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
