ocfs2: Use GFP_NOFS in kmalloc during localalloc window move
kmalloc() during a localalloc window move can trigger the mm to prune
the dcache which inturn can trigger the fs to delete an inode causing
it start a recursive transaction.
The fix also makes the change in kmalloc during localalloc shutdown
just to be safe.
Fixes oss bugzilla#901
