Theodore Ts'o 246307745c ext4: optimize ext4_es_shrink() ... When the system is under memory pressure, ext4_es_srhink() will get called very often. So optimize returning the number of items in the file system's extent status cache by keeping a per-filesystem count, instead of calculating it each time by scanning all of the inodes in the extent status cache. Also rename the slab used for the extent status cache to be "ext4_extent_status" so it's obviousl the slab in question is created by ext4.
