Same issue in openat02:

# env PATH=`pwd`:$PATH ./openat02
openat02    1  TPASS  :  test O_APPEND for openat success
openat02    2  TPASS  :  test O_CLOEXEC for openat success
openat02    3  TPASS  :  test O_LARGEFILE for openat success
openat02    4  TCONF  :  openat02.c:242: test O_NOATIME flag for openat needs filesystems which are mounted without noatime and relatime
openat02    5  TPASS  :  test O_NOFOLLOW for openat success
openat02    6  TPASS  :  test O_TRUNC for openat success
openat02    0  TWARN  :  tst_tmpdir.c:206: tst_rmdir: rmobj(/tmp/opeim4IKK) failed: lstat(/tmp/opeim4IKK/large_file) failed; errno=75: Value too large for defined data type
