* NFS: Add sysfs links to sunrpc clients for nfs_clientsBenjamin Coddington2023-06-191-0/+2
| | | | | | | | For the general and state management nfs_client under each mount, create symlinks to their respective rpc_client sysfs entries. Signed-off-by: Benjamin Coddington <bcodding@redhat.com> Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
* NFS: add superblock sysfs entriesBenjamin Coddington2023-06-191-0/+5
| | | | | | | | | | | | | Create a sysfs directory for each mount that corresponds to the mount's nfs_server struct. As the mount is being constructed, use the name "server-n", but rename it to the "MAJOR:MINOR" of the mount after assigning a device_id. The rename approach allows us to populate the mount's directory with links to the various rpc_client objects during the mount's construction. The naming convention (MAJOR:MINOR) can be used to reference a particular NFS mount's sysfs tree.

* NFS: Make all of /sys/fs/nfs network-namespace uniqueBenjamin Coddington2023-06-191-0/+1
| | | | | | | | | | | | Expand the NFS network-namespaced sysfs from /sys/fs/nfs/net down one level into /sys/fs/nfs by moving the "net" kobject onto struct nfs_netns_client and setting it up during network namespace init. This prepares the way for superblock kobjects within /sys/fs/nfs that will only be visible to matching network namespaces.

* NFS: rename nfs_client_kobj to nfs_net_kobjBenjamin Coddington2023-06-191-1/+1
| | | | | | | Match the variable names to the sysfs structure. Signed-off-by: Benjamin Coddington <bcodding@redhat.com> Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
* NFSv4: Fix up RCU annotations for struct nfs_netns_clientTrond Myklebust2020-10-151-1/+1
| | | | | | | | | | The identifier is read as an RCU protected string. Its value may be changed during the lifetime of the network namespace by writing a new string into the sysfs pseudofile (at which point, we free the old string only after a call to synchronize_rcu()).

* NFS: Use the correct style for SPDX License IdentifierNishad Kamdar2020-05-271-1/+1
| | | | | | | | | | | | | | | This patch corrects the SPDX License Identifier style in header file related to NFS Client support. For C header files Documentation/process/license-rules.rst mandates C-like comments (opposed to C source files where C++ style should be used). Changes made by using a script provided by Joe Perches here: https://lkml.org/lkml/2019/2/7/46.

* NFS: Add sysfs support for per-container identifierTrond Myklebust2019-07-061-0/+10
| | | | | | | | | In order to identify containers to the NFS client, we add a per-net sysfs attribute that udev can fill with the appropriate identifier. The identifier could be a unique hostname, but in most cases it will probably be a persisted uuid. Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
