Hello, Please consider backporting to 4.14.y the following commit from kernel-net-next by Vlastimil Babka [CC'ed]:
d6a24df00638 ("mm, page_alloc: actually ignore mempolicies for high priority allocations") It cherry-picks cleanly and builds fine.
The reason for the request is that the commit 1d26c112959f http://stash.eng.vyatta.net:7990/projects/VC/repos/linux-vyatta/commits/1d26c112959f ("mm, page_alloc:do not break __GFP_THISNODE by zonelist reset") that was previously backported to 4.14.y broke some of our functionality after we upgraded from an earlier 4.14 kernel without the fix.
Well, that's very surprising! Could you be more specific about what exactly got broken?
The reason this is happening is not clear, with this commit only found by bisect. Fortunately the requested commit resolves the issue.
I would like to understand the problem first, because I currently can't imagine how the first commit could break something and the second fix it.
