Subject: [RFC][PATCH 0/3] spin_unlock_wait and assorted borkage
Date: Tue, 24 May 2016 16:27:23 +0200 [thread overview]
Message-ID: <20160524142723.178148277@infradead.org> (raw)
As per recent discussions spin_unlock_wait() has an unintuitive 'feature'.
lkml.kernel.org/r/20160520053926.GC31084@linux-uzut.site
These patches pull the existing solution into generic code; annotate all
spin_unlock_wait() users and fix nf_conntrack more.
The alternative -- putting smp_acquire__after_ctrl_dep() into
spin_unlock_wait() can be done later if desired, now that al users are audited
and corrected.
Please (very) carefully consider.
