Subject: [PATCH 13/15] IB/hfi1: Keep SC_USER as the last send context type
Date: Thu, 12 May 2016 10:23:47 -0700 [thread overview]
Message-ID: <20160512172346.9741.19872.stgit@scvm10.sc.intel.com> (raw)
In-Reply-To: <20160512172050.9741.84190.stgit-9QXIwq+3FY+1XWohqUldA0EOCMrvLtNR@public.gmane.org>
From: Jianxin Xiong <jianxin.xiong-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>
SC_USER needs to be the last send context type to ensure other
send context types get their allocation when num_user_contexts
is set to a large number.
This fixes a panic when the module parameter num_user_contexts
is set to 141 and larger.
