mm/oom_kill.c: In function ‘task_will_free_mem’:
mm/oom_kill.c:767: warning: ‘ret’ may be used uninitialized in this function
If __task_will_free_mem() is never called inside the for_each_process()
loop, ret will not be initialized.

Untested. I'm not familiar with the code, hence the default value of
true was deducted from the logic in the loop (return false as soon as
__task_will_free_mem() has returned false).
