Revision 7d638093d4b0e9ef15bd78f38f11f126e773cc14 authored by Vladimir Davydov on 10 June 2015, 18:14:46 UTC, committed by Linus Torvalds on 10 June 2015, 23:43:43 UTC
When trimming memcg consumption excess (see memory.high), we call
try_to_free_mem_cgroup_pages without checking if we are allowed to sleep
in the current context, which can result in a deadlock. Fix this.
Fixes: 241994ed8649 ("mm: memcontrol: default hierarchy interface for memory")
