Subject: memcg: more mem_cgroup_uncharge() batching
From: Hugh Dickins <hughd@xxxxxxxxxx>
It seems odd that truncate_inode_pages_range(), called not only when
truncating but also when evicting inodes, has mem_cgroup_uncharge_start
and _end() batching in its second loop to clear up a few leftovers, but
not in its first loop that does almost all the work: add them there too.
