LLVM report compiling error:
/kpathsamples/bpf/tracex5_kern.c:33:15: error: use of undeclared identifier
'__NR_getuid'; did you
mean '__NR_vgetcpu'?
if (sd.nr >= __NR_getuid && sd.nr <= __NR_getsid) {
^~~~~~~~~~~
__NR_vgetcpu
/kpath/arch/x86/include/uapi/asm/vsyscall.h:7:2: note: '__NR_vgetcpu' declared
here
__NR_vgetcpu,
This patch fix it by adding asm/unistd.h to it.
