From 1e1093c7fd4951bb4272212c238d09cd7a22f5fc Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Thu, 1 Nov 2012 16:44:05 -0400 Subject: [PATCH] NFSv4.1: Don't mess with task priorities in nfs41_setup_sequence We want to preserve the rpc_task priority for things like writebacks, that may have differing levels of urgency.
