Title:
Bionic update: upstream stable patchset 2018-05-29
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Bionic:
Fix Released
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 following upstream
stable patches should be included in the Ubuntu kernel:
