Tycho Andersen 88282297ff selftests/seccomp: fix build on older kernels ... The seccomp selftest goes to some length to build against older kernel headers, viz. all the #ifdefs at the beginning of the file. Commit 201766a20e ("ptrace: add PTRACE_GET_SYSCALL_INFO request") introduces some additional macros, but doesn't do the #ifdef dance. Let's add that dance here to avoid: gcc -Wl,-no-as-needed -Wall seccomp_bpf.c -lpthread -o seccomp_bpf In file included from seccomp_bpf.c:51: seccomp_bpf.c: In function ‘tracer_ptrace’: seccomp_bpf.c:1787:20: error: ‘PTRACE_EVENTMSG_SYSCALL_ENTRY’ undeclared (first use in this function); did you mean ‘PTRACE_EVENT_CLONE’?
