Re: linux-image 4.3.3 bcache stability patches

Hello list, Ben,

Would it be possible to include latest bcache stability patches from
https://github.com/torvalds/linux/compare/master...ewheelerinc:bcache-patches-for-3.17
According bcache developers (Kent Overstreet and others) it merges
fine from 3.17 up to 4.4 as they concerns only bcache driver:

bcache/btree.c
bcache/super.c
bcache/writeback.c
bcache/writeback.h

see https://lkml.org/lkml/2015/12/29/379

This should improve SSD lockups.

Thank you

Martin
And then some for the good, whole bcache including these stability patches can be backported from 3.17 to 3.16, just tested:
