[Petr Vorel]

Hi Zhao,

FYI this required adding const:

unlinkat01.c:43:13: warning: initialization discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
   43 |         {0, testfile, 0, 0},
      |             ^~~~~~~~
unlinkat01.c:45:13: warning: initialization discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
   45 |         {0, testfile, 0, ENOTDIR},
      |             ^~~~~~~~
unlinkat01.c:46:15: warning: initialization discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
   46 |         {100, testfile, 0, EBADF},
      |               ^~~~~~~~
unlinkat01.c:47:13: warning: initialization discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
   47 |         {0, testfile, 9999, EINVAL},
      |             ^~~~~~~~
unlinkat01.c:48:20: warning: initialization discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
   48 |         {AT_FDCWD, testfile, 0, 0},
      |                    ^~~~~~~~
unlinkat01.c:49:13: warning: initialization discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
   49 |         {0, subpathname, AT_REMOVEDIR, 0},
      |             ^~~~~~~~~~~

Please next time try to not introduce new warnings.

Thanks, merged!

Kind regards,
Petr
