Hello,
In cgroup v1, dealing with cgroup membership was difficult because the
number of membership associations was unbound. As a result, cgroup v1
grew several controllers whose primary purpose is either tagging
membership or pull in configuration knobs from other subsystems so

Implement kernfs_walk_and_get() which is similar to
kernfs_find_and_get() but can walk a path instead of just a name.

cgroup_is_descendant() currently walks up the hierarchy and compares
each ancestor to the cgroup in question. While enough for cgroup core
usages, this can't be used in hot paths to test cgroup membership.

This patch adds the extension for the xt_cgroup2 which matches packets

Implement cgroup_get_path() using kernfs_walk_and_get() which obtains
a default hierarchy cgroup from its path. This will be used to allow
cgroup path based matching from outside cgroup proper -
e.g. networking and perf.

This patch implements xt_cgroup2 which matches cgroup2 membership of
the associated socket. The match is recursive and invertible.
For rationales on introducing another cgroup based match, please refer
to a preceding commit "sock, cgroup: add sock->sk_cgroup".
