Subject: NFSD: Make the file_delayed_close workqueue UNBOUND
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ce7df05508c30de140c1dfd9a32a8c03c5671ecc;p=linux.git

NFSD: Make the file_delayed_close workqueue UNBOUND

workqueue: nfsd_file_delayed_close [nfsd] hogged CPU for >13333us 8
	times, consider switching to WQ_UNBOUND

There's no harm in closing a cached file descriptor on another core.
