From 46a5ab4754cad6aeefd96feae8ba65db8655e1af Mon Sep 17 00:00:00 2001 From: Peng Tao Date: Fri, 13 Jun 2014 23:02:25 +0800 Subject: [PATCH] nfs: allow to specify cred in nfs_initiate_pgio so that flexfile layout client can pass in DS credential instead of using user cred, which will be done in the next patch.
