Subject: bpf: Move cgroup iterator helpers to bpf.h
X-Git-Tag: v6.1.151~100
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2f7877e003fa68af4932ebad345763282e9466db;p=thirdparty%2Fkernel%2Fstable.git

bpf: Move cgroup iterator helpers to bpf.h

[ Upstream commit 9621e60f59eae87eb9ffe88d90f24f391a1ef0f0 ]

Move them into bpf.h given we also need them in core code.
