[PATCH] add wait_event_interruptible_exclusive() macro
This patch defines a macro that does exactly what
wait_event_interruptible() does except that it adds the current task to the
wait queue as an exclusive task (i.e., sets the WQ_FLAG_EXCLUSIVE flag)
rather than as a non-exclusive task as wait_event_interruptible() does.
This allows one to do a wake_up_nr() to wake up a specific number of tasks.
I'm in the process of submitting a patch to linux-ia64 that requires this
capability. (Its subject line is "[PATCH 3/4] SGI Altix cross partition
functionality".)
