Subject: [PATCH 0/3] fs/proc: do_task_stat: use sig->stats_lock
Date: Tue, 23 Jan 2024 16:33:13 +0100 [thread overview]
Message-ID: <20240123153313.GA21832@redhat.com> (raw)
do_task_stat() has the same problem as getrusage() had before
getrusage-use-sig-stats_lock-rather-than-lock_task_sighand.patch
3/3 depends on the patch above.
Oleg.
