Subject: [PATCH-v3 04/17] staging/lustre: don't assert ln_refcount in LNetGetId
Date: Mon, 15 Jul 2013 22:27:07 +0800	[thread overview]
Message-ID: <1373898440-14208-5-git-send-email-bergwolf@gmail.com> (raw)
In-Reply-To: <1373898440-14208-1-git-send-email-bergwolf@gmail.com>

If LNetNIInit() fails, we'll get zero ln_refcount. So fail
LNetGetId() properly instead of asserting.

We can get to it when socklnd fails to scan network interfaces,
which is possible if Lustre is builtin.
