Subject: [PATCH 00/19 v2] SUNRPC: clean up server thread management
Date: Tue, 23 Nov 2021 12:29:35 +1100	[thread overview]
Message-ID: <163763078330.7284.10141477742275086758.stgit@noble.brown> (raw)

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.
