Hi Andrew, After merging the akpm-current tree, today's linux-next build (arm multi_v7_defconfig) produced this warning:
mm/oom_kill.c: In function '__oom_reap_task': mm/oom_kill.c:537:2: warning: 'mm' may be used uninitialized in this function [-Wmaybe-uninitialized] mmput_async(mm); ^ Introduced by commit df1e2f56632d ("oom_reaper: close race with exiting task") This is real - the first "goto unlock_oom" is before "mm" has been assigned. -- Cheers, Stephen Rothwell
