Subject: selftests/cgroup: fix cg_run_in_subcgroups ignoring arg parameter
Date: Thu, 20 Aug 2026 15:09:44 +0800

cg_run_in_subcgroups() discards its arg and always passes NULL to
cg_run(), turning the (void *)100 from test_kmem_dead_cgroups() into NULL
so no allocation occurs.

This makes test_kmem_dead_cgroups() falsely pass without exercising the
"dying cgroup with charged slab" scenario it intends to test.

Pass the arg through to cg_run() to fix this.
