From 4b1e84ed8883d4f24f99417cb84165ff77a99d66 Mon Sep 17 00:00:00 2001 From: Peng Tao Date: Mon, 15 Jul 2013 22:27:07 +0800 Subject: [PATCH] staging/lustre: don't assert ln_refcount in LNetGetId 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.
