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?
