Subject: [RFC PATCH 0/3] sched: membarrier updates
Date: Fri, 14 Aug 2020 12:43:55 -0400	[thread overview]
Message-ID: <20200814164358.4783-1-mathieu.desnoyers@efficios.com> (raw)

Hi,

Please find those three changes based on our recent discussions about
interaction between membarrier and exit_mm and kthread_use_mm. I added
documentation of memory ordering scenarios to membarrier.c as well.

Thanks,

Mathieu
