From 33e638b9070ba5e8812836e20390da6a6af13900 Mon Sep 17 00:00:00 2001 From: "Srivatsa S. Bhat" Date: Tue, 6 Dec 2011 23:18:12 +0100 Subject: [PATCH] PM / Sleep: Use the freezer_count() functions in [un]lock_system_sleep() APIs Now that freezer_count() and freezer_do_not_count() don't have the restriction that they are effective only when called by userspace processes, use them in lock_system_sleep() and unlock_system_sleep() instead of open-coding their parts.
