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:

The conflict in #2 is due to the change 43711a479c1eb38a6c4836e31fddd5599aa95884 "bcache: fix high CPU occupancy during journal" which was applied as part of https://bugs.launchpad.net/bugs/1784665.

description: updated

Did not include commit "cxl: Fix kobject memleak" while applying due to a build failure on ppc64el (thank you to Kamal for pointing this out.) All other patches sent to the ML in this set are now on xenial/master-next
