  "message": "bpf/arena: Add bpf_arena_map_kern_vm_start() and bpf_prog_arena()\n\nstruct bpf_arena is opaque to callers outside arena.c. Add two helpers\nfor struct_ops subsystems that need to reach into an arena:\n\n  bpf_arena_map_kern_vm_start(struct bpf_map *map)\n    returns @map\u0027s kern_vm_start. A sched_ext follow-up needs this\n    to translate kern_va \u003c-\u003e uaddr.\n\n  bpf_prog_arena(struct bpf_prog *prog)\n    returns the bpf_map of the arena referenced by @prog (NULL if\n    @prog references no arena). The verifier enforces at most one\n    arena per program. Used by struct_ops callers that auto-discover\n    an arena from a member prog and need to take a map reference.\n\nSuggested-by: Kumar Kartikeya Dwivedi \u003cmemxor@gmail.com\u003e\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nReviewed-by: Emil Tsalapatis \u003cemil@etsalapatis.com\u003e\nLink: https://lore.kernel.org/r/20260522172219.1423324-6-tj@kernel.org\nSigned-off-by: Alexei Starovoitov \u003cast@kernel.org\u003e\n",
