Review request for mesos and Benjamin Mahler. Repository: mesos Description ------- Introduces the controller process for perf event which was also present in cgroups1. The controller is automatically enabled, and should not be visible inside the cgroups.controllers file in the root cgroup. As a consequence, we will not be able to manually enable or disable this controller via writing to the cgroup.subtree_control file. Reference: perf_event section in https://docs.kernel.org/admin-guide/cgroup-v2.html slide 34 in https://man7.org/conf/ndctechtown2021/cgroups-v2-part-1-intro-NDC-TechTown-2021-Kerrisk.pdf Diffs ----- src/CMakeLists.txt 963d4201afeec0b5b4cdcd5b4bfbbddf466b22c7 src/Makefile.am 779b893fca3fa2cfe28be1bb9571a44383579ede src/slave/containerizer/mesos/isolators/cgroups2/cgroups2.cpp 76c8df9b10ff8142c89a812f24acb8c6accc0ae5 src/slave/containerizer/mesos/isolators/cgroups2/constants.hpp 1fb713837b53180fa97d7bbe58ee8f6e638e75fc src/slave/containerizer/mesos/isolators/cgroups2/controllers/perf_event.hpp PRE-CREATION src/slave/containerizer/mesos/isolators/cgroups2/controllers/perf_event.cpp PRE-CREATION Diff: https://reviews.apache.org/r/74997/diff/1/ Testing ------- Thanks, Jason Zhou
