Title:
Focal update: v5.4.9 upstream stable release
Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Focal:
Confirmed
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:
v5.4.9 upstream stable release
