[PATCH bpf-next v3 10/11] libbpf: Fix accessing syscall arguments on riscv

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



riscv's syscall handlers get "unpacked" arguments instead of a
struct pt_regs pointer. Indicate this to libbpf using
PT_REGS_SYSCALL_REGS macro.
