Subject: mm/thp/autonuma: use TNF flag instead of vm fault
X-Git-Tag: v4.11-rc1~76^2~36
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=9a8b300f2f7812ebf4630b8b40499da38b38e882;p=linux.git

mm/thp/autonuma: use TNF flag instead of vm fault

We are using the wrong flag value in task_numa_falt function.  This can
result in us doing wrong numa fault statistics update, because we update
num_pages_migrate and numa_fault_locality etc based on the flag argument
passed.

Fixes: bae473a423 ("mm: introduce fault_env")
