Move the inline code for waking up writers to a new function
ttwwakeup(). The conditions for doing the wakeup will soon become more complicated and I don't want them duplicated in all drivers. It's probably not worth making ttwwakeup() a macro or an inline function. The cost of the function call is relatively small when there is a process to wake up. There is usually a process to wake up for large writes and the system call overhead dwarfs the function call overhead for small writes.
