Wong xfs_bmap_add_free isn't a block mapping function; it schedules deferred freeing operations for a later point in a compound transaction chain. While it's primarily used by bunmapi, its use has expanded beyond that. Move it to xfs_alloc.c and rename the function since it's now general freeing functionality. Bring the slab cache bits in line with the way we handle the other intent items. Signed-off-by: Darrick J.
