Subject: [PATCH v2] eal: cleanup alarm and multiprocess hotplug before memory detach
Date: Wed, 21 Dec 2022 11:41:52 +0800 [thread overview]
Message-ID: <20221221034152.30628-1-changfengnan@bytedance.com> (raw)
Alarm and multiprocess hotplug still need access hugepage memory,
if alarm event processed after memory detach, it may cause SEGV.
So cleanup alarm and multiprocess hotplug before memory detach.
Fixes: 90b13ab8d4f7 ("alarm: remove direct access to interrupt handle")
Fixes: a0cc7be20dd1 ("mem: cleanup multiprocess resources")
