(2) afs_vnode_invalid: Log when the server's callback promise for a vnode is no longer valid and we need to refetch the vnode metadata. (3) afs_dir_invalid: Log when the contents of a directory are marked invalid and requiring refetching from the server and the cache invalidating. and two tracepoints to record data version number management: (4) afs_set_dv: Log when the DV is recorded on a vnode. (5) afs_dv_mismatch: Log when the DV recorded on a vnode plus the expected delta for the operation does not match the DV we got back from the server.
