So it took a few more minutes. I'm testing it again, not on NFS, and now the creation of empty filesystem took just a few seconds and empty file is ~160MB. This sounds much better. So please write a test, using something like truncate -s3T image mkfs.ext4 image mount && write some data convert && rollback Thanks. Later we might need to add some mkfs.ext4 option coverage. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
