Suren Baghdasaryan	5b53573671	libprocessgroup: restrict SetupCgroups to one-time usage and only by init ... SetupCgroups is called by init process during early-init stage and is not supposed to be called again by anyone else. Ensure that the caller is the init process, make sure cgroup.rc file is written only one time, keep the file descriptor to cgroup.rc file open by the init process to ensure all its further mappings stay valid even if the file is deleted. Bug: 124774415 Test: build, run, verify no errors or warning in the logcat Change-Id: Ib8822cf0112db7744e28d442182d54dcf06f46f2 Signed-off-by: Suren Baghdasaryan <surenb@google.com>	2019-03-28 01:25:22 +00:00

Suren Baghdasaryan	82b72a5667	libprocessgroup: Add support for task profiles ... Abstract usage of cgroups into task profiles that allows for changes in cgroup hierarchy and version without affecting framework codebase. Rework current processgroup and sched_policy API function implementations to use task profiles instead of hardcoded paths and attributes. Mount cgroups using information from cgroups.json rather than from init.rc Exempt-From-Owner-Approval: already approved in internal master Bug: 111307099 Test: builds, boots Change-Id: If5532d6dc570add825cebd5b5148e00c7d688e32 Merged-In: If5532d6dc570add825cebd5b5148e00c7d688e32 Signed-off-by: Suren Baghdasaryan <surenb@google.com>	2019-02-03 16:48:35 +00:00
