[LTP] [PATCH] fs_fill: switch the SAFE MACROs back to ordinary syscall

[Li Wang <liwang@redhat.com>]

To fix those brokens:
  safe_macros.c:225: BROK: tst_fill_fs.c:43: open(mntpoint/thread48/file0,65,0700) failed: ENOSPC
  safe_macros.c:169: BROK: fs_fill.c:49: mkdir(mntpoint/thread21,0700) failed: ENOSPC
