to get rid of warning you proposing to do 1k line renames?! Just add: +#undef R8 +#undef R9 +#undef R10 #define R0 BPF_REG_0 Though I think the better fix woud be to clean up: arch/x86/include/uapi/asm/ptrace-abi.h What's the point of: #define R8 72 from 'uapi' point of view? Look like kernel details that shouldn't be exposed in uapi. -- To unsubscribe from this list: send the line "unsubscribe netdev" in
