Darrick J. Wong	f83d436aef	xfs: increase the default parallelism levels of pwork clients ... Increase the parallelism level for pwork clients to the workqueue defaults so that we can take advantage of computers with a lot of CPUs and a lot of hardware. On fast systems this will speed up quotacheck by a large factor, and the following posteof/cowblocks cleanup series will use the functionality presented in this patch to run garbage collection as quickly as possible. We do this by switching 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. Signed-off-by: Darrick J.

Darrick J. Wong	3e5a428b26	xfs: poll waiting for quotacheck ... Create a pwork destroy function that uses polling instead of uninterruptible sleep to wait for work items to finish so that we can touch the softlockup watchdog. IOWs, gross hack.
