H A Dtrace.ha9507f6a Sun Jul 09 10:45:29 CDT 2023 Chuck Lever <chuck.lever@oracle.com> NFSD: Replace nfsd_prune_bucket()

Enable nfsd_prune_bucket() to drop the bucket lock while calling
kfree(). Use the same pattern that Jeff recently introduced in the
NFSD filecache.

A few percpu operations are moved outside the lock since they
temporarily disable local IRQs which is expensive and does not
need to be done while the lock is held.
