We've had a longstanding lockdep splat in open_fs_devices that we've been ignoring for some time, since it's not actually a problem. However this has been masking all the other lockdep issues that we have, since lockdep takes its ball and goes home as soon as you hit one problem. This fixes all the issues I found while running xfstests. I would like to do something more sane around fs_devices in the future, but for right now lets just get these lockdep things gone so we can focus on more important things, as well as get notifications on any new lockdep issues that show up. Thanks, Josef
