Do you have a msg-id to the patch that has been tested?
message_id: 20180910125513.311-2-mho...@kernel.org
Thanks! It woudl be really great if this was a part of the report when
testing patches which are not mainline yet.
This patch resulting in a crash is quite surprising. The patch is RFC
and not tested yet but I will definitely have a look. Could you help me
some more and give faddr2line __oom_reap_task_mm+0x40 please?
$ faddr2line ./vmlinux __oom_reap_task_mm+0x40
__oom_reap_task_mm+0x40/0x175:
can_madv_dontneed_vma at mm/internal.h:48
(inlined by) __oom_reap_task_mm at mm/oom_kill.c:505
