Subject: [PATCH 0/3 for 4.2] sys_membarrier (x86, generic)
Date: Wed, 17 Jun 2015 08:10:44 -0400 [thread overview]
Message-ID: <1434543047-7015-1-git-send-email-mathieu.desnoyers@efficios.com> (raw)
Hi,
I am submitting the membarrier system call for the upcoming Linux 4.2
merge window. It would be nice if it could sit a few days in Andrew
Morton's tree before that.
A major addition to sys_membarrier changelog is the inclusion of the
list of users which would benefit from having this system call today.
Thanks,
Mathieu
