Josef Bacik 6ef5ed0d38 Btrfs: add ioctl and incompat flag to set the default mount subvol ... This patch needs to go along with my previous patch. This lets us set the default dir item's location to whatever root we want to use as our default mounting subvol. With this we don't have to use mount -o subvol=<tree id> anymore to mount a different subvol, we can just set the new one and it will just magically work. I've done some moderate testing with this, mostly just switching the default mount around, mounting subvols and the default mount at the same time and such, everything seems to work. Thanks, Older kernels would generally be able to still mount the filesystem with the default subvolume set, but it would result in a different volume being mounted, which could be an even more unpleasant suprise for users. So if you set your default subvolume, you can't go back to older kernels.
