Subject: [PATCH 0/3] nohz: Convert tick dependency mask to atomic_t
Date: Thu, 24 Mar 2016 15:37:58 +0100 [thread overview]
Message-ID: <1458830281-4255-1-git-send-email-fweisbec@gmail.com> (raw)
As per Linus suggestion, lets convert the tick dependency mask to
atomic_t. Introduce atomic_fetch_or() and confine fetch_or() back to
scheduler guts.

HEAD: 7b7e5da5733f58668181077ec394a718e08c392c
Thanks,
