[LTP] [PATCH 1/2] Add FS quota availability check functions

[Petr Vorel]

Hi Martin,

Actually, there is a warning:
tst_supported_fs_types.c: In function ‘tst_check_quota_support’:
tst_supported_fs_types.c:117:59: warning: passing argument 4 of ‘quotactl’ discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
  117 |  TEST(quotactl(QCMD(Q_QUOTAON, USRQUOTA), device, format, quotafile));

Would you prefer to cast to char *, or just change function parameter to char *?

Kind regards,
Petr
