Hey Andrey, Zach,
So I'm back from my vacation, and have found that the Android team has
released a -compat tree for their 3.4 kernel. Basically this tree
re-adds some items like earlysuspend and classic wakelocks in order to
provide better compatibility with old (and by old, I really mean current
as far as we see - so ICS and earlier) Android userland.
Since we're still shipping ICS, and have no access to whatever the
Android 5.0 userland will be, it seems merging in the -compat tree would
make sense.
However, I know Tixy and others have already tried to address the lack
of earlysuspend in the android-3.3+ kernels, so I wanted to double check
that this wouldn't cause additional pain (since those adjustments might
need to be reverted).
So I just wanted to check first with folks to make sure there are no
objections to merging in the -compat changes, and that the timing of
merging in these changes isn't problematic (I can happily hold off till
this months release is done, so we don't risk any last minute gotchas).
The only worry I can see is that now even vanilla versions of LT kernels
are basing off llct that includes Androidizaton, even vanilla will have
possibly invasive wakelock code.
It might be good to briefly audit the changes to confirm they don't
appear if CONFIG_ANDROID is off. Google might not take much care about
that case but I think it might be important for us.
-Andy
