PERF_RECORD_MISC_USER : > + PERF_RECORD_MISC_KERNEL; - unbalanced curly braces - missing curly brace for multi-line statement. - unnecessary line-break due to col80 warning from checkpatch > +extern struct perf_guest_info_callbacks *perf_guest_cbs; > +extern int perf_register_guest_info_callbacks( > + struct perf_guest_info_callbacks *); > +extern int perf_unregister_guest_info_callbacks( > + struct perf_guest_info_callbacks *); - unnecessary line-break due to col80 warning from checkpatch > +static inline int perf_register_guest_info_callbacks > +(struct perf_guest_info_callbacks *) {return 0; } > +static inline int perf_unregister_guest_info_callbacks > +(struct perf_guest_info_callbacks *) {return 0; } - invalid C: function parameter needs name even if unused - missing space after opening curly brace Please provide delta fixes.
