This is a revision of my series for cleaning up server thread
management.
Currently lockd, nfsd, and nfs-callback all manage threads slightly
differently. This series unifies them.
Changes since first series include:
- minor bug fixes
- kernel-doc comments for new functions
- split first patch into 3, and make the bugfix a separate patch
- fix management of pool_maps so lockd can usse svc_set_num_threads
safely
- switch nfs-callback to not request a 'pooled' service.

NeilBrown (19):
SUNRPC/NFSD: clean up get/put functions.
NFSD: handle error better in write_ports_addfd()
SUNRPC: stop using ->sv_nrthreads as a refcount
nfsd: make nfsd_stats.th_cnt atomic_t
SUNRPC: use sv_lock to protect updates to sv_nrthreads.
NFSD: narrow nfsd_mutex protection in nfsd thread
NFSD: Make it possible to use svc_set_num_threads_sync
SUNRPC: discard svo_setup and rename svc_set_num_threads_sync()
NFSD: simplify locking for network notifier.
lockd: introduce nlmsvc_serv
lockd: simplify management of network status notifiers
lockd: move lockd_start_svc() call into lockd_create_svc()
lockd: move svc_exit_thread() into the thread
lockd: introduce lockd_put()
lockd: rename lockd_create_svc() to lockd_get()
SUNRPC: move the pool_map definitions (back) into svc.c
SUNRPC: always treat sv_nrpools==1 as "not pooled"
lockd: use svc_set_num_threads() for thread start and stop
NFS: switch the callback service back to non-pooled.
