From: Rafael J. Wysocki Date: Tue, 20 Oct 2009 04:45:02 +0000 (+0200) Subject: PM: Make warning in suspend_test_finish() less likely to happen X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=04bf7539c08d64184736cdc5e4ad617eda77eb0f;p=openwrt%2Fstaging%2Fblogic.git PM: Make warning in suspend_test_finish() less likely to happen Increase TEST_SUSPEND_SECONDS to 10 so the warning in suspend_test_finish() doesn't annoy the users of slower systems so much. Also, make the warning print the suspend-resume cycle time, so that we know why the warning actually triggered. Patch prepared during the hacking session at the Kernel Summit in Tokyo.
