xfs: increase the default parallelism levels of pwork clients

2021-02-03T17:18:49Z

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. Wong Reviewed-by: Christoph Hellwig Reviewed-by: Brian Foster

xfs: poll waiting for quotacheck

2019-07-03T15:21:58Z

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. Signed-off-by: Darrick J. Wong Reviewed-by: Brian Foster
