  "message": "bpf: Add support for certain atomics in bpf_arena to x86 JIT\n\nSupport atomics in bpf_arena that can be JITed as a single x86 instruction.\nInstructions that are JITed as loops are not supported at the moment,\nsince they require more complex extable and loop logic.\n\nJITs can choose to do smarter things with bpf_jit_supports_insn().\nLike arm64 may decide to support all bpf atomics instructions\nwhen emit_lse_atomic is available and none in ll_sc mode.\n\nbpf_jit_supports_percpu_insn(), bpf_jit_supports_ptr_xchg() and\nother such callbacks can be replaced with bpf_jit_supports_insn()\nin the future.\n\nSigned-off-by: Alexei Starovoitov \u003cast@kernel.org\u003e\nAcked-by: Eduard Zingerman \u003ceddyz87@gmail.com\u003e\nLink: https://lore.kernel.org/r/20240405231134.17274-1-alexei.starovoitov@gmail.com\nSigned-off-by: Martin KaFai Lau \u003cmartin.lau@kernel.org\u003e\n",
