dm thin: reduce endio_hook pool size
commit 7768ed33ccdc02801c4483fc5682dc66ace14aea upstream.
Reduce the slab size used for the dm_thin_endio_hook mempool.
Allocation has been seen to fail on machines with smaller amounts
of memory due to fragmentation.
lvm: page allocation failure. order:5, mode:0xd0
device-mapper: table: 253:38: thin-pool: Error creating pool's endio_hook mempool
