Now that it does nothing when lk->filename[0] == '\0', this could be
de-indented a little:
if (!lk->filename[0])
return;
if (lk->fd >= 0)
close(lk->fd);
unlink_or_warn(lk->filename);
lk->filename[0] = 0;
This could technically double-close if interrupted by a signal that
tries to remove the file again, right? Should this use
close_lock_file which sets fd to -1 before closing?
if (!lk->filename[0])
return;
close_lock_file(lk);
unlink_or_warn(lk->filename);
lk->filename[0] = 0;
With or without such changes,
