Patch 2 adds the selftest: the\nexisting cpu_flag subtests always prime a key with BPF_F_ALL_CPUS\nfirst, so the create path is not covered today.\n\nv1: https://lore.kernel.org/bpf/20260920093153.439743-1-donggeunyoo.kernel@gmail.com/\nv2: https://lore.kernel.org/bpf/20260923000801.1764758-1-donggeunyoo.kernel@gmail.com/\n\nChanges in v3:\n - patch 1: key init_cpu on BPF_F_CPU rather than on onallcpus (Leon\n   Hwang)\n - patch 1: re-flow the paragraph naming pcpu_copy_value() (BPF CI AI\n   review)\n - patch 2: pin the thread across the delete and the create, and name a\n   CPU other than the pinned one, so the BPF_F_NO_PREALLOC arm does not\n   depend on staying put (BPF CI AI review)\n\nChanges in v2:\n - patch 1: cover the BPF_F_CPU entry condition in the block comment\n   above pcpu_init_value() (BPF CI AI review, Alexei Starovoitov)\n - patch 2: skip the new subtests instead of failing them on a\n   uniprocessor machine (Sashiko AI review)\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n\nLink: https://patch.msgid.link/20260924102321.2120434-1-donggeunyoo.kernel@gmail.com\nSigned-off-by: Alexei Starovoitov \u003cast@kernel.org\u003e\n",
