As per Bruce's request submitting the client and server series together as there is a common patch that's needed by both. No client side changes were made since the previous submission v6 server-side changes --- removed global copy notify list and instead relying only on the idr list of stateids. Laundromat now traverses that list and if copy notify state wasn't referenced in a lease period, state is deleted. --- removed storing parent's stid pointer in the copy notify state. instead storing the parent's stateid and client id then using it to lookup the stid structure and client structure during validation of the stateid of the READ. --- added a refcount to the copy notify state to make sure only 1 will delete it (as it can be delete either by the nfs4_put_stid(), laundromat, or offload_cancel op. basically all access to the copy state is using just one global lock now (netd->s2s_cp_lock). --- added a type to the copy_stateid_t to distinguish copy notify state kept by the source server and copy state used by the destination server. --- previously with a global copy notify list, the check if client has state before unmounting checked if the list was empty, now the code traverses the idr list and looks for anything with a matching clientid (again under the global s2s_cp_lock).
