There is a patch that changes mmp_blk to (long long)mmp_blk which should prevent the MMP block from overwriting block filesystem data. A patch has been provided but it has not been inspected from bug24209 mmp_blk64.patch. We would like this patch to be evaluated. </p> <p>We are concerned if we have current customers who have full filesystems and enable MPP they could be putting data at risk. </p> LU-268

Possible bug in userspace block handling when enabling MPP
