From 01a527ec7c62efea601a39f0cd8e6a8517259014 Mon Sep 17 00:00:00 2001 From: Nishanth Aravamudan Date: Mon, 7 Nov 2005 01:01:14 -0800 Subject: [PATCH] drivers/acpi: fix-up schedule_timeout() usage Use schedule_timeout_interruptible() instead of set_current_state()/schedule_timeout() to reduce kernel size. Also use msecs_to_jiffies() instead of direct HZ division to avoid rounding errors.
