[PATCH] filtered wakeups: wakeup enhancements
From: William Lee Irwin III <wli@holomorphy.com>
This patch provides an additional argument to __wake_up_common() so that the
information wakefunc.patch made waiters ready to receive may be passed to them
by wakers. This is provided as a separate patch so that the overhead of the
additional argument to __wake_up_common() can be measured in isolation. No
change in performance was observable here.
