From: Sergey Matyukevich <sergey.matyukevich@xxxxxxxxxxxx> Define appropriate uapi for the BPF_PROG_TYPE_PERF_EVENT program type by exporting the user_regs_struct structure instead of the pt_regs structure that is in-kernel only. Signed-off-by: Sergey Matyukevich <sergey.matyukevich@xxxxxxxxxxxx> --- Originally I sent this patch via linux-snps-arc mailing list: see [1]. However this patch accompanies ARC support for libbpf bpf_tracing.h accepted to bpf kernel tree: see [2]. So it looks like it makes sense to post this patch here as well. I will also update linux-snps-arc patch series accordingly.
