Bug description:
SRU Justification
Impact: CONFIG_RT_GROUP_SCHED was enabled in focal, except for the
lowlatency kernel since we expected most RT users to use that kernel.
However we are getting RT regressions with the generic kernel. Digging
deeper into this option, it seems to be pretty specialized and to
require quite a bit of workload-specific configuration/tuning to be
useful, so it doesn't really seem to make sense for a general-purpose
kernel.
Fix: Turn this option back off.
Test Case: See comment #4.
Regression Potential: This was turned on to support some docker
functionality, so this functionality will no longer be available.
We've had this option off for all releases prior to focal, so this
seems acceptable.
