2021-12-10libutils: do not follow process's groupWei Wang
1) App doesn't have cgroup access and there is no purpose of reading cgroup for app. For system_server it should be known in foreground group. So there is no benefit of reading group. 2) Reading cgroup in apps can also cause contention for other cgroup operations. 3) vendor can change cgroup setting and get_sched_policy may return incorrect information for get_sched_policy_profile_name.

2020-08-24Fix API for C compatibilityGreg Kaiser
In https://android-review.googlesource.com/c/platform/system/core/+/1224544 when we introduced a default argument to androidSetThreadPriority(), we broke C compatibility with this API, and with the header file in general. We fix this up by instead introducing a new method that takes three arguments. This gets this header file compiling for C again, and keeps this particular API C compatible. Any C++ callers of the three argument version of androidSetThreadPriority() will need to switch to using androidSetThreadPriorityAndPolicy(). Although since this was a recent change, we believe there is only one such user, which we are fixing at the same time.
