Initial patches already accepted by Canonical on 117275. Patchset posted to community, waiting on
review. (I had posted a version of the patchset in Dec after fixing minor comments. Waiting to hear back from community )

Never mind.

'git describe' seems to think they are in 3.19-rcX but they are
not in 3.19.

$ git describe fd979c0
v3.19-rc2-62-gfd979c0

$ git describe aaea361
v3.19-rc4-172-gaaea361

They were merged on Feb 2, so they should be in 4.0
