Commit 449bf8d0 authored by Linus Torvalds's avatar Linus Torvalds

Merge branch 'nfsd-next' of git://linux-nfs.org/~bfields/linux

Pull nfsd changes from Bruce Fields:
 "This includes miscellaneous bugfixes and cleanup and a performance fix
  for write-heavy NFSv4 workloads.

  (The most significant nfsd-relevant change this time is actually in
  the delegation patches that went through Viro, fixing a long-standing
  bug that can cause NFSv4 clients to miss updates made by non-nfs users
  of the filesystem.  Those enable some followup nfsd patches which I
  have queued locally, but those can wait till 3.14)"

* 'nfsd-next' of git://linux-nfs.org/~bfields/linux: (24 commits)
  nfsd: export proper maximum file size to the client
  nfsd4: improve write performance with better sendspace reservations
  svcrpc: remove an unnecessary assignment
  sunrpc: comment typo fix
  Revert "nfsd: remove_stid can be incorporated into nfs4_put_delegation"
  nfsd4: fix discarded security labels on setattr
  NFSD: Add support for NFS v4.2 operation checking
  nfsd4: nfsd_shutdown_net needs state lock
  NFSD: Combine decode operations for v4 and v4.1
  nfsd: -EINVAL on invalid anonuid/gid instead of silent failure
  nfsd: return better errors to exportfs
  nfsd: fh_update should error out in unexpected cases
  nfsd4: need to destroy revoked delegations in destroy_client
  nfsd: no need to unhash_stid before free
  nfsd: remove_stid can be incorporated into nfs4_put_delegation
  nfsd: nfs4_open_delegation needs to remove_stid rather than unhash_stid
  nfsd: nfs4_free_stid
  nfsd: fix Kconfig syntax
  sunrpc: trim off EC bytes in GSSAPI v2 unwrap
  gss_krb5: document that we ignore sequence number
