Subject: [PATCH 0/2] fix premature OOM killer
Date: Fri, 19 May 2017 13:26:02 +0200	[thread overview]
Message-ID: <20170519112604.29090-1-mhocko@kernel.org> (raw)

Hi,
this is a follow up for [1]. The first patch is what Tetsuo suggested
[2], I've just added a changelog for it. This one should be merged
as soon as possible. The second patch is still an RFC. I _believe_
that it is the right thing to do but I haven't checked all the PF paths
which return VM_FAULT_OOM to be sure that there is nobody who would return
this error when not doing a real allocation.
