[PATCH 00/11] nfsd: deny mode handling overhaul

[Jeff Layton <jlayton@primarydata.com>]

Here is the deny mode handling overhaul broken out into a separate
series, as requested by Christoph. I've tried to address most of
his review comments, but I may have missed some. Let me know if
if I did.

Part of the client_mutex removal series involves cleaning up the
handling of deny modes in the server in order to setting and
enforcement atomic.

This does add a new per-nfs4_file spinlock, but in principle it
should never be contended while the client_mutex is still wrapped
around all of this code.

Jeff Layton (8):
  nfsd: refactor nfs4_file_get_access and nfs4_file_put_access
  nfsd: remove nfs4_file_put_fd
  nfsd: shrink st_access_bmap and st_deny_bmap
  nfsd: set stateid access and deny bits in nfs4_get_vfs_file
  nfsd: clean up reset_union_bmap_deny
  nfsd: always hold the fi_lock when bumping fi_access refcounts
  nfsd: make deny mode enforcement more efficient and close races in it
  nfsd: cleanup and rename nfs4_check_open

Trond Myklebust (3):
  nfsd: Add fine grained protection for the nfs4_file->fi_stateids list
  nfsd: Add locking to the nfs4_file->fi_fds[] array
  nfsd: clean up helper __release_lock_stateid
