From: Darrick J. Wong <djwong@kernel.org>

Switch the pwork workqueue to unbounded, since the current user
(quotacheck) runs lengthy scans for each work item and we don't care
about dispatching the work on a warm cpu cache or anything like that.
Also set WQ_SYSFS so that we can monitor where the wq is running.
