Al Viro f71f94845e um: fix oopsable race in line_close() ... tty->count is decremented only after ->close() had been called and several tasks can hit it in parallel. As the result, using tty->count to check if you are the last one is broken. We end up leaving line->tty not reset to NULL and the next IRQ on that sucker will blow up trying to dereference pointers from kfree'd struct tty. Fix is obvious: we need to use a counter of our own.
