Subject: wake_up vs. wake_up_sync
Date: Wed, 27 Jun 2001 13:18:43 -0700	[thread overview]
Message-ID: <3B3A3FA3.B482B78B@swiftview.com> (raw)

I'm having trouble understanding the difference between these.
Synchronous apparently causes try_to_wake_up() to NOT call
reschedule_idle() but I'm uncertain what reschedule_idle() is doing. I
assume it just looks for an idle CPU and makes that CPU reschedule.

What is the purpose of wake_up_sync? Why would you want to prevent
reschedule_idle()?
