Description
While debugging a hanging nfs mount on a client shortly after an nfs server restart, I got the impression that the client must have lost an osp->os_ref_count. Reading code showed:
deleg_reopen() calls get_next_deleg_stream() in a loop but does not bother to call open_stream_rele() on the "goto retry" path (EAGAIN). This leaks one osp->os_ref_count.
