Subject: [PATCH v1 0/3] Fix cgroup1 support in get from fd/file interfaces
Date: Mon, 10 Oct 2022 23:58:42 +0000 [thread overview]
Message-ID: <20221010235845.3379019-1-yosryahmed@google.com> (raw)
commit f3a2aebdd6fb ("cgroup: enable cgroup_get_from_file() on cgroup1")
enabled using cgroup_get_from_file() and cgroup_get_from_fd() on
cgroup1, to enable bpf cgroup_iter to attach to cgroup1.
Apparently, other callers depended on these functions only supporting
cgroup2. Revert f3a2aebdd6 and add new separate interfaces that support
both cgroup1 and cgroup2.
