Subject: [PATCH] mm: Mark the OOM reaper thread as freezable
Date: Sat, 18 Sep 2021 16:39:20 -0700	[thread overview]
Message-ID: <20210918233920.9174-1-sultan@kerneltoast.com> (raw)

From: Sultan Alsawaf <sultan@kerneltoast.com>

The OOM reaper thread uses wait_event_freezable() without actually being
marked as freezable. Fix it by adding a set_freezable() call.

Fixes: aac453635549 ("mm, oom: introduce oom reaper")
