Seems like this only enables statx(2) test on specific arches, even if
current arch has wired up statx syscall.
For example, I noticed as for 4.11-rc6 kernel, many platforms have
enabled statx syscall:
eguan@eguan:~/workspace/src/kernel$ git lo | grep -i "wire up statx"
1493aa6 xtensa: wire up statx system call
fdfe4a3 generic syscalls: Wire up statx syscall
e3b1ebd m68k: Wire up statx
f717629 powerpc: Wire up statx() syscall
63d32d1 parisc: Wire up statx system call
a1016e9 ARM: wire up statx syscall
8bd49ac s390: wire up statx system call
9cb74b5 MIPS: Wire up statx system call
But many of them are not covered in this test. (Tested with ppc64 host
and test _notrun there.)
How about including <sys/syscall.h> to get __NR_statx definition first
and define our own syscall number only if it's not yet defined?
Thanks,
