But it doesn't. No -- all that the remount,ro sees is that there's a fd still open for write. It has no idea if or when that fd is going to get closed, so it should fail. Returning -EBUSY is the only thing it _can_ do: waiting for the fs to be remountable might wait forever. So the fs is still writable after that point. --Stephen - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
