-Subject: oom: improve oom disable handling
-
-From: Michal Hocko <mhocko@suse.com>

-[ Upstream commit d75da004c708c9fca7b53f7da293a295522414d9 ]
-
-Tetsuo has reported that sysrq triggered OOM killer will print a
-misleading information when no tasks are selected:
-
-  sysrq: SysRq : Manual OOM execution
-  Out of memory: Kill process 4468 ((agetty)) score 0 or sacrifice child
-  Killed process 4468 ((agetty)) total-vm:43704kB, anon-rss:1760kB, file-rss:0kB, shmem-rss:0kB
-  sysrq: SysRq : Manual OOM execution
-  Out of memory: Kill process 4469 (systemd-cgroups) score 0 or sacrifice child
-  Killed process 4469 (systemd-cgroups) total-vm:10704kB, anon-rss:120kB, file-rss:0kB, shmem-rss:0kB
-  sysrq: SysRq : Manual OOM execution
-  sysrq: OOM request ignored because killer is disabled
-  sysrq: SysRq : Manual OOM execution
-  sysrq: OOM request ignored because killer is disabled
-  sysrq: SysRq : Manual OOM execution
-  sysrq: OOM request ignored because killer is disabled
-
-The real reason is that there are no eligible tasks for the OOM killer
-to select but since commit 7c5f64f84483 ("mm: oom: deduplicate victim
-selection code for memcg and global oom") the semantic of out_of_memory
-has changed without updating moom_callback.
-
-This patch updates moom_callback to tell that no task was eligible which
-is the case for both oom killer disabled and no eligible tasks.  In
-order to help distinguish first case from the second add printk to both
-oom_killer_{enable,disable}.  This information is useful on its own
-because it might help debugging potential memory allocation failures.
