Merge tag 'nfs-for-5.8-1' of git://git.linux-nfs.org/projects/anna/linux-nfs
Pull NFS client updates from Anna Schumaker: "New features and improvements: - Sunrpc receive buffer sizes only change when establishing a GSS credentials - Add more sunrpc tracepoints - Improve on tracepoints to capture internal NFS I/O errors Other bugfixes and cleanups: - Move a dprintk() to after a call to nfs_alloc_fattr() - Fix off-by-one issues in rpc_ntop6 - Fix a few coccicheck warnings - Use the correct SPDX license identifiers - Fix rpc_call_done assignment for BIND_CONN_TO_SESSION - Replace zero-length array with flexible array - Remove duplicate headers - Set invalid blocks after NFSv4 writes to update space_used attribute - Fix direct WRITE throughput regression" * tag 'nfs-for-5.8-1' of git://git.linux-nfs.org/projects/anna/linux-nfs: (27 commits) NFS: Fix direct WRITE throughput regression SUNRPC: rpc_xprt lifetime events should record xprt->state xprtrdma: Make xprt_rdma_slot_table_entries static nfs: set invalid blocks after NFSv4 writes NFS: remove redundant initialization of variable result sunrpc: add missing newline when printing parameter 'auth_hashtable_size' by sysfs NFS: Add a tracepoint in nfs_set_pgio_error() NFS: Trace short NFS READs NFS: nfs_xdr_status should record the procedure name SUNRPC: Set SOFTCONN when destroying GSS contexts SUNRPC: rpc_call_null_helper() should set RPC_TASK_SOFT SUNRPC: rpc_call_null_helper() already sets RPC_TASK_NULLCREDS SUNRPC: trace RPC client lifetime events SUNRPC: Trace transport lifetime events SUNRPC: Split the xdr_buf event class SUNRPC: Add tracepoint to rpc_call_rpcerror() SUNRPC: Update the RPC_SHOW_SOCKET() macro SUNRPC: Update the rpc_show_task_flags() macro SUNRPC: Trace GSS context lifetimes SUNRPC: receive buffer size estimation values almost never change ...
