[Audit-test-developer] [PATCH v3 2/5] audit-test: handle __NR3264_xxx syscall definitions

[AKASHI T. <tak...@li...>]

On some architectures including arm64, system call numbers are defined
in /usr/include/asm-generic/unistd.h. This file contains irregular
style of definitions like
    #define __NR3264_truncate 45
    #define __NR_truncate __NR3264_truncate
(In fact, it's more complicated.)

This patch takes care of such cases.
