Subject: [PATCH 07/13] RDS: Workaround for in-use MRs on close causing crash
Date: Thu, 11 Mar 2010 15:50:01 -0800	[thread overview]
Message-ID: <1268351407-7394-8-git-send-email-andy.grover@oracle.com> (raw)
In-Reply-To: <1268351407-7394-1-git-send-email-andy.grover@oracle.com>

if a machine is shut down without closing sockets properly, and
freeing all MRs, then a BUG_ON will bring it down. This patch
changes these to WARN_ONs -- leaking MRs is not fatal (although
not ideal, and there is more work to do here for a proper fix.)
