Subject: riscv, bpf: Add missing uapi header for BPF_PROG_TYPE_PERF_EVENT programs
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=eb9928bed003dd61a443d0ba51ae066429fbe735;p=linux.git

riscv, bpf: Add missing uapi header for BPF_PROG_TYPE_PERF_EVENT programs

Add missing uapi header the BPF_PROG_TYPE_PERF_EVENT programs by
exporting struct user_regs_struct instead of struct pt_regs which is
in-kernel only.
