[PATCH 1/8] PM: Add suspend block api.
Adds /sys/power/policy that selects the behaviour of /sys/power/state. After setting the policy to opportunistic, writes to /sys/power/state become non-blocking requests that specify which suspend state to enter when no suspend blockers are active. A special state, "on", stops the process by activating the "main" s... 28 May 2010 10:25

[PATCH 3/8] PM: suspend_block: Abort task freezing if a suspend_blocker is active.
If a suspend_blocker is active, suspend will fail anyway. Since try_to_freeze_tasks can take up to 20 seconds to complete or fail, aborting as soon as someone blocks suspend (e.g. from an interrupt handler) improves the worst case wakeup latency. On an older kernel where task freezing could fail for processes att... 14 May 2010 00:51
