# HEAD: e79f15a4598c1f3f3f7f3319ca308c63c91fdaf2 x86/resctrl: Add task resctrl information display

The main change in this tree is the extension of the resctrl procfs ABI
with a new file that helps tooling to navigate from tasks back to resctrl
groups: /proc/{pid}/cpu_resctrl_groups.

Also fix static key usage for certain feature combinations and simplify
the task exit resctrl case.
