[ACTIVITY] (John Stultz) Apr 30 - May 4

[John Stultz]

=== Highlights ===
* Got further feedback from DaveC on the volatile ranges work.  I need 
to rework the patch significantly to use the falloc interface instead of 
fadvise in order to allow the functionality to be more generic and 
implementable on a per-filesystem basis (as there are lots of fs 
specific tricks that can be used). Despite his insistence that I rework 
it, he did say that he was interested in seeing the functionality added, 
since he has some ideas for how it can be used w/ xfs.  Started the 
process of figuring out how to refactor the code to be per-fs, ideally 
without rewriting most of it.

* Further review and quite a bit of discussion around community 
CLOCK_TAI groundwork and improved leapsecond processing.  Also got into 
a big discussion with a researcher on UTC-SLS (smoothed leap second) 
which allows applications to avoid the nasty leapsecond by smearing it 
over ~15 minutes. All interesting, but getting both features to not 
conflict and work together will be interesting. Submitted a example RFC 
of how I'd like to see CLOCK_TAI implemented.

* Wrote up some blueprints for possible  future Android related work 
focusing on debugging 
technology.https://blueprints.launchpad.net/linux-linaro/+spec/android-debugging

* Reported a compile bug w/ omap-usb-host.c caused by a not-so-recent 
commit.  The proper fix was merged shortly there after.

* Updated linaro-android-3.4 tree and made a few corrections at Andrey's 
request.


=== Plans ===
* Continue reworking volatile ranges to use fadvise.

* Will be on vacation from May 9th-16th.
