[PATCH 0/4] SUNRPC: Various RCU fixes

[Anna Schumaker <anna@kernel.org>]

From: Anna Schumaker <Anna.Schumaker@Netapp.com>

These are various fixes that I found after turning on CONFIG_LOCKDEP,
CONFIG_PROVE_RCU, and CONFIG_DEBUG_ATOMIC_SLEEP. I didn't hit any issues
when testing against a Linux server, but running against Netapp with pNFS
had several different lockdep & rcu related spews show up in my dmesg
(and that's just from running cthon, not even xfstests). These patches fix
all the issues that I found, and have a couple extra cleanups that I noticed
along the way.

Thoughts?
Anna
