Subject: Reminder for feature dev->power.power_state removal date July 2007
Date: Fri, 03 Jul 2009 07:36:48 +0530	[thread overview]
Message-ID: <1246586808.2530.8.camel@jaswinder.satnam> (raw)

Hello Pavel,

What:   dev->power.power_state
When:   July 2007
Why:    Broken design for runtime control over driver power states, confusing
        driver-internal runtime power management with:  mechanisms to support
        system-wide sleep state transitions; event codes that distinguish
        different phases of swsusp "sleep" transitions; and userspace policy
        inputs.  This framework was never widely used, and most attempts to
        use it were broken.  Drivers should instead be exposing domain-specific
        interfaces either to kernel or to userspace.
Who:    Pavel Machek <pavel@suse.cz>

If you are facing any issue regarding feature removal kindly update the
"Documentation/feature-removal-schedule.txt" like what you are waiting
for.

Thanks,
