NFS: Merge CONFIG_NFS_V4_1 with CONFIG_NFS_V4

2026-01-30T16:42:21+00:00

Compiling the NFSv4 module without any minorversion support doesn't make much sense, so this patch sets NFS v4.1 as the default, always enabled NFS version allowing us to replace all the CONFIG_NFS_V4_1s scattered throughout the code with CONFIG_NFS_V4. Signed-off-by: Anna Schumaker

NFSv4.1: pass transport for callback shutdown

2025-11-23T20:30:12+00:00

When we are setting up the 4.1 callback server, we pass in the appropriate rpc_xprt transport pointer with which to associate the callback server structure. Similarly, pass in the rpc_xprt pointer for when we are shutting down the callback. This will be used to make sure that we free the server structure and then clear the rpc_xprt's bc_server pointer in a safe manner. Signed-off-by: Olga Kornievskaia Signed-off-by: Trond Myklebust

NFSv4: Add CB_GETATTR support for delegated attributes

2024-07-08T17:47:25+00:00

When the client holds an attribute delegation, the server may retrieve all the timestamps through a CB_GETATTR callback. Signed-off-by: Trond Myklebust Signed-off-by: Lance Shelton Reviewed-by: Jeff Layton Signed-off-by: Trond Myklebust Signed-off-by: Anna Schumaker

NFSv4, NFSD: move enum nfs_cb_opnum4 to include/linux/nfs4.h

NFSv4: Track the number of referring calls in struct cb_process_state

2024-01-04T15:47:56+00:00

When the server gives us a set of referring calls, to tell us that the NFSv4.1 callback needs to be ordered with respect to those calls, then we may want to make that information available to the operations. In certain cases, it may allow them to optimise their behaviour due to the extra knowledge. Signed-off-by: Trond Myklebust Signed-off-by: Anna Schumaker

NFSv4.1: Fix uninitialised variable in devicenotify

When decode_devicenotify_args() exits with no entries, we need to ensure that the struct cb_devicenotifyargs is initialised to { 0, NULL } in order to avoid problems in nfs4_callback_devicenotify(). Reported-by: Signed-off-by: Trond Myklebust Signed-off-by: Anna Schumaker

NFSv4: Add support for CB_RECALL_ANY for flexfiles layouts

2020-03-16T12:34:30+00:00

When we receive a CB_RECALL_ANY that asks us to return flexfiles layouts, we iterate through all the layouts and look at whether or not there are active open file descriptors that might need them for I/O. If there are no such descriptors, we return the layouts. Signed-off-by: Trond Myklebust
