Only bpf programs are prevented from attaching to these\nfunctions. The rest of the tracing shouldn\u0027t be affected.\n\n[note: Peter ok-ed the patch, Alexei rewrote commit log]\n\nFixes: 378b7708194f (\"sched: Make migrate_{en,dis}able() inline\")\nSigned-off-by: Yonghong Song \u003cyonghong.song@linux.dev\u003e\nAcked-by: Menglong Dong \u003cmenglong.dong@linux.dev\u003e\nLink: https://lore.kernel.org/r/20251029183646.3811774-1-yonghong.song@linux.dev\nSigned-off-by: Alexei Starovoitov \u003cast@kernel.org\u003e\n",
