Meeting Agenda]]


=== ARM Status ===
Q/master: lp1176977 ("XFS instability on armhf under load") - cherry
picked two
more patches that address the free space fragmentation: the resulting
kernel
passes all tests so far, i'm waiting for user feedback and one last
batch of
tests.
*/highbank: lp1182637("cpu_offlining fails to run on ARM") - all the
highbanks kernel that
we released so far are affected by this - basically, you can offline a
cpu but
when you try to put it back, reinsetion fails and the only way to get
the cpu back
is to reboot. Debugged till the point the cpu is plugged back, but it
never really
starts and pick up the idle thread - i'll probably need to do a comparison
between the boot environment (when the cpu are added to the system via
the same
mechanism) and this scenario.

=== Release Metrics and Incoming Bugs ===
Release metrics and incoming bug data can be reviewed at the following
link:

=== Milestone Targeted Work Items ===
I'm still working on cleaning up our team's set of work items and
getting monthly goals properly refelcted in the blueprints.

=== Status: Saucy Development Kernel ===
Our Saucy unstable branch has been rebased to the latest v3.10-rc3
upstream kernel. Saucy master-next is currently at v3.9.3. I
anticipate we'll cut over to v3.10 around the -rc4 time frame.
On the phablet side, we now have Ubuntu kernels in the archive for the
Nexus 4, 7, 10, and Galaxy Nexus devices. We also anticipate an
AppArmor pull request next week from the security team to get the latest
AppArmor patches into these kernels.
Important upcoming dates:
Thurs June 20 - Alpha 1 (opt in)

=== Status: CVE's ===
