Go on, seems that there was never a real usecase for that. According to the original post, it was to test resizer: http://thread.gmane.org/gmane.linux.file-systems/20355 "mount -o alloc_start=num forces allocation hints to start at least num bytes into the disk. This was introduced to test the resizer." I'll probably remove it from mkfs as well. -- 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
