Merge tag 'nfsd-4.6' of git://linux-nfs.org/~bfields/linux
Pull nfsd updates from Bruce Fields: "Various bugfixes, a RDMA update from Chuck Lever, and support for a new pnfs layout type from Christoph Hellwig. The new layout type is a variant of the block layout which uses SCSI features to offer improved fencing and device identification. (Also: note this pull request also includes the client side of SCSI layout, with Trond's permission.)" * tag 'nfsd-4.6' of git://linux-nfs.org/~bfields/linux: sunrpc/cache: drop reference when sunrpc_cache_pipe_upcall() detects a race nfsd: recover: fix memory leak nfsd: fix deadlock secinfo+readdir compound nfsd4: resfh unused in nfsd4_secinfo svcrdma: Use new CQ API for RPC-over-RDMA server send CQs svcrdma: Use new CQ API for RPC-over-RDMA server receive CQs svcrdma: Remove close_out exit path svcrdma: Hook up the logic to return ERR_CHUNK svcrdma: Use correct XID in error replies svcrdma: Make RDMA_ERROR messages work rpcrdma: Add RPCRDMA_HDRLEN_ERR svcrdma: svc_rdma_post_recv() should close connection on error svcrdma: Close connection when a send error occurs nfsd: Lower NFSv4.1 callback message size limit svcrdma: Do not send Write chunk XDR pad with inline content svcrdma: Do not write xdr_buf::tail in a Write chunk svcrdma: Find client-provided write and reply chunks once per reply nfsd: Update NFS server comments related to RDMA support nfsd: Fix a memory leak when meeting unsupported state_protect_how4 nfsd4: fix bad bounds checking
