Overview: As replication technology we want to use DISCARDs only if they really zero the backing storage. Thin LVM does it but claims not to do it. To make that reasonably usable with DRBD we added this "discard_zeroes_if_aligned" hack^H^H^H^H configure option. Please see the commit messages for all the details. Please add it to your for-4.7/drivers branch. Thanks!
