similar to: BTRFS default subvolume identification and use

This fixes the issue I had come across with the default subvolume not being set/used on btrfs when isntalling via `extlinux --install /boot/syslinux`.

I am new to syslinux/extlinux. Can I boot from a linux btrfs subvolume? I am getting "Failed to load ldlinux.c32" when I attempt to boot from a btrfs subvolume. Setup: 1) I have a USB disk with one partition. The partition is marked "active". 2) I make a btrfs filesystem with "mkfs.btrfs /dev/sdd1". I mount the partiton and execute "btrfs su create root".

The algorithm for btrfs subvolume search seems to be completely braindead, and at least in the current Linux kernels there are ioctls

It's needed to enumerate both UFS1/2 since they have different magic numbers and super block offsets. Besides, UFS2 can be installed in the 0-64k range like BTRFS, whereas UFS1 can't.

If we change our default subvolume, btrfs receive will fail to find subvolume. To fix this problem, we have three ideas: 1.make btrfs snapshot ioctl support passing source subvolume''s objectid. 2.when we want to using interval subvolume path, we mount it other place that use subvolume 5 as its default subvolume. 3.tell the user to mount the toplevel subvol by himself and run receive
