DESCRIPTION
The vfs_getvfs function returns the mount point structure for a file system given its file system identifier. The file system ID should have been allocated by calling vfs_getnewfsid(9); otherwise, it will not be found. A major user of vfs_getvfs is NFS, which uses the
.Vt fsid as part of file handles in order to determine the file system a given RPC is for. If vfs_getvfs fails to find the mount point related to fsid, the file system is considered stale.
RETURN VALUES
If fsid is found, the mount point for the ID is returned; otherwise, NULL is returned.
PSEUDOCODE
if ((mp = vfs_getvfs(&fhp->fh_fsid)) == NULL) {
error = ESTALE;
goto out;
}
