From cdd9ade711599e7672a635add0406080856f8b92 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Wed, 28 May 2014 10:33:00 -0400 Subject: [PATCH] xprtrdma: mount reports "Invalid mount option" if memreg mode not supported If the selected memory registration mode is not supported by the underlying provider/HCA, the NFS mount command reports that there was an invalid mount option, and fails. This is misleading. Reporting a problem allocating memory is a lot closer to the truth.
