Subject: [PATCH 34/70] 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
