Hi,
while playing with jackd on 2.6.24-rcx, I found poll() timing out too early.
That is: earlier than its timeout argument specified.
Setting poll()'s timeout argument to "required timeout" + "1 jiffy in ms"
fixed it. Patch below should fix it too. Correct?
Untested.
Otherwise 2.6.24-rc5 ticks just fine here, thanks.

Make sys_poll() wait at least timeout ms
schedule_timeout(jiffies) waits for at least jiffies - 1.
Add 1 jiffie to the timeout_jiffies calculated in sys_poll() to wait at least
timeout_msecs, like poll() manpage says.
