Title:
Xenial update to 4.4.115 stable release
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Xenial:
Fix Committed
Bug description:
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 4.4.115 upstream
stable stable patch set is now available. It should be included
in the Ubuntu kernel as well.
