Merge tag 'nfsd-5.2' of git://linux-nfs.org/~bfields/linux
Pull nfsd updates from Bruce Fields: "This consists mostly of nfsd container work: Scott Mayhew revived an old api that communicates with a userspace daemon to manage some on-disk state that's used to track clients across server reboots. We've been using a usermode_helper upcall for that, but it's tough to run those with the right namespaces, so a daemon is much friendlier to container use cases. Trond fixed nfsd's handling of user credentials in user namespaces. He also contributed patches that allow containers to support different sets of NFS protocol versions. The only remaining container bug I'm aware of is that the NFS reply cache is shared between all containers. If anyone's aware of other gaps in our container support, let me know. The rest of this is miscellaneous bugfixes" * tag 'nfsd-5.2' of git://linux-nfs.org/~bfields/linux: (23 commits) nfsd: update callback done processing locks: move checks from locks_free_lock() to locks_release_private() nfsd: fh_drop_write in nfsd_unlink nfsd: allow fh_want_write to be called twice nfsd: knfsd must use the container user namespace SUNRPC: rsi_parse() should use the current user namespace SUNRPC: Fix the server AUTH_UNIX userspace mappings lockd: Pass the user cred from knfsd when starting the lockd server SUNRPC: Temporary sockets should inherit the cred from their parent SUNRPC: Cache the process user cred in the RPC server listener nfsd: Allow containers to set supported nfs versions nfsd: Add custom rpcbind callbacks for knfsd SUNRPC: Allow further customisation of RPC program registration SUNRPC: Clean up generic dispatcher code SUNRPC: Add a callback to initialise server requests SUNRPC/nfs: Fix return value for nfs4_callback_compound() nfsd: handle legacy client tracking records sent by nfsdcld nfsd: re-order client tracking method selection nfsd: keep a tally of RECLAIM_COMPLETE operations when using nfsdcld nfsd: un-deprecate nfsdcld ...
