A couple tests have been uploaded to http://openbenchmarking.org/result/1206152- STEA-VMTESTS05.
Note for the nodatacow, the subvolume did have a snapshot, since the point was for VM's that could be snapshoted (either through virsh or btrfs). Thus the first write to a block was cow, but subsequent ones where not. FY, the tests are not very thorough yet -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
