Eduard Zingerman 48b13cab1e bpf: Allow specifying bpf_fastcall attribute for BPF helpers ... Allow a new optional 'Attributes' section to be specified for helper functions description, e.g.: * u32 bpf_get_smp_processor_id(void) * ... * Return * ... * Attributes * __bpf_fastcall * Generated header for the example above: #ifndef __bpf_fastcall #if __has_attribute(__bpf_fastcall) #define __bpf_fastcall __attribute__((bpf_fastcall)) #else #define __bpf_fastcall #endif #endif ... __bpf_fastcall static __u32 (* const bpf_get_smp_processor_id)(void) = (void *) 8; The following rules apply: - when present, section must follow 'Return' section; - attribute names are specified on the line following 'Attribute' keyword; - attribute names are separated by spaces; - section ends with an "empty" line (" *\n"). Valid attribute names are recorded in the ATTRS map. ATTRS maps shortcut attribute name to correct C syntax.
