SYS_getdents undecleared for readdir regression test on arm64

[Po-Hsu Lin]

In the regression test, readdir.c will fail to compile on arm64 and fail the test_regression_testsuite test.

cc -g -O0 -Wall -Wstrict-prototypes readdir.c -lapparmor -o readdir
readdir.c: In function ‘main’:
readdir.c:45:14: error: ‘SYS_getdents’ undeclared (first use in this function)
  if (syscall(SYS_getdents, fd, &dir, sizeof(struct dirent)) == -1){
              ^~~~~~~~~~~~
readdir.c:45:14: note: each undeclared identifier is reported only once for each function it appears in
<builtin>: recipe for target 'readdir' failed
make: *** [readdir] Error 1

For arm64, there is only "SYS_getdents64" available:
$ grep -Ir SYS_getdents /usr/include/
/usr/include/aarch64-linux-gnu/bits/syscall.h:#define SYS_getdents64 __NR_getdents64
/usr/include/aarch64-linux-gnu/bits/syscall.h:#define SYS_getdents64 __NR_getdents64

Patch added to q-r-t in commit https://git.launchpad.net/qa-regression-testing/commit/?id=52f39f87176843398bce2190d96a5aad0da2bf4f so is available for the kernel autotests.

Closing the qrt task.

@Po-Hsu Lin is this still an issue or can we close this now?

Hi Colin,

Just verified again manually on a ARM64 node. I can't see this SYS_getdents error message anymore.
Thank you!
