From 6aa98f6217861889523e38b0141c8c71b2ef8a83 Mon Sep 17 00:00:00 2001 From: Sergey Matyukevich Date: Thu, 14 Apr 2022 11:11:26 +0300 Subject: [PATCH] ARC: bpf: define uapi for BPF_PROG_TYPE_PERF_EVENT program type 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.
