Hi Petr

    I have seen kernel source about quota and try it. I think you are right.  But current quota_v1
and quota_v2 detection has problem. In kernel source, I disable CONFIG_QFMT_V2 and enable CONFIG_QFMT_V1
,then I found ltp still detects quotav2 instead of quotav1,  and run ./quotactl01, the following error occurs:

./quotactl01
