Suren Baghdasaryan 5e2f1d9167 ANDROID: make per-cgroup PSI tracking configurable ... With cgroup v2 hierarchy enabled PSI accounts stalls for each cgroup separately and aggregates at each level of the hierarchy. That causes additional overhead since psi_avgs_work would be called for each cgroup in the hierarchy. In Android we use PSI only at the system level, therefore this overhead can be avoided. Introduce CONFIG_PSI_PER_CGROUP_ACCT that controls per-cgroup PSI tracking and is disabled by default.
