Merge patch series "Introduce bpf_cgroup_read_xattr"
Song Liu <song@kernel.org> says:
Introduce a new kfunc bpf_cgroup_read_xattr, which can read xattr from
cgroupfs nodes. The primary users are LSMs, cgroup programs, and sched_ext.
* patches from https://lore.kernel.org/20250623063854.1896364-1-song@kernel.org:
selftests/bpf: Add tests for bpf_cgroup_read_xattr
bpf: Mark cgroup_subsys_state->cgroup RCU safe
bpf: Introduce bpf_cgroup_read_xattr to read xattr of cgroup's node
kernfs: remove iattr_mutex
