From e42837bcd35b75bb59ae5d3e62f87be1aeeb05c3 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Thu, 18 Oct 2007 03:04:45 -0700 Subject: freezer: introduce freezer-friendly waiting macros Introduce freezer-friendly wrappers around wait_event_interruptible() and wait_event_interruptible_timeout(), originally defined in , to be used in freezable kernel threads. Make some of the freezable kernel threads use them. This is necessary for the freezer to stop sending signals to kernel threads, which is implemented in the next patch. Signed-off-by: Rafael J.
