[syzbot ci]

syzbot ci has tested the following series

[v1] bpf trampoline support "jmp" mode
https://lore.kernel.org/all/20251114092450.172024-1-dongml2@chinatelecom.cn
* [PATCH RFC bpf-next 1/7] ftrace: introduce FTRACE_OPS_FL_JMP
* [PATCH RFC bpf-next 2/7] x86/ftrace: implement DYNAMIC_FTRACE_WITH_JMP
* [PATCH RFC bpf-next 3/7] bpf: fix the usage of BPF_TRAMP_F_SKIP_FRAME
* [PATCH RFC bpf-next 4/7] bpf,x86: adjust the "jmp" mode for bpf trampoline
* [PATCH RFC bpf-next 5/7] bpf: introduce bpf_arch_text_poke_type
* [PATCH RFC bpf-next 6/7] bpf,x86: implement bpf_arch_text_poke_type for x86_64
* [PATCH RFC bpf-next 7/7] bpf: implement "jmp" mode for trampoline

and found the following issue:
