...th the prebuilt binary from kernel.org which failed to identify that I had set a non 0 value via `btrfs subvolume set-default <id> <path>`. In extlinux/main.c there appears to be two different unique attempts to grab information relating to default subvolume. If the first one succeeds, `find_device_btrfs(path)`, the second is not ran, `find_device`, which in turn would call `get_default_subvol`. I found by commenting out line 1293 of extlinux/main.c that since it skips `find_device_btrfs(path)` the subvolume is set properly and I can continue to boot from subvolume and rely on set-default to work...

From: Raphael S. Carvalho <raphael.scarv at gmail.com> Change since v1: * Fix bug on dentry structure (thank you specification; btw, sarcasm), and consequently a bug on ufs_readdir. * Add readlink support (applied tests for symlinks whose destionation path were stored in blk pointers and the file itself). * Several improvements. Wrote the documentation below. I think it would be good to
