Xenial update to v4.4.41 stable release

[Tim Gardner]

SRU Justification

    Impact:
       The upstream process for stable tree updates is quite similar
       in scope to the Ubuntu SRU process, e.g., each patch has to
       demonstrably fix a bug, and each patch is vetted by upstream
       by originating either directly from a mainline/stable Linux tree or
       a minimally backported form of that patch. The v4.4.41 upstream stable
       patch set is now available. It should be included in the Ubuntu
       kernel as well.

       git://git.kernel.org/

    TEST CASE: TBD

Status changed to 'Confirmed' because the bug affects multiple users.

[Breno Leitão (breno-leitao)]

Hello,

Any idea when the kernel with this fix will be made available?

Thanks
