Subject: Re: [PATCH 41/47]
1. We can read -ioctx_table only once and we do not read rcu_read_lock()
or even rcu_dereference().
This mm has no users, nobody else can play with -ioctx_table. Otherwise
the code is buggy anyway, if we need rcu_read_lock() in a loop because
-ioctx_table can be updated then
It is possible for limit - setpoint + 1 to equal zero, leading to a
divide by zero error. Blindly adding 1 to limit - setpoint is not
working, so we need to actually test the divisor before calling div64.

But exit_aio() looks obviously unnecessarily overcomplicated, I was

Current code only touches the direction register when setting direction
to output, which breaks logic like
echo high /sys/class/gpio/gpio0/direction
which is expected to also set the value. This patch also adds a call
to update the value register when setting direction to output.
