See containerd/btrfs PR 40 and moby/moby PR 44761. (Thanks to [@]neersighted.) The containerd/btrfs library now requires headers from kernel 4.12 or newer: - https://github.com/torvalds/linux/blob/master/include/uapi/linux/btrfs.h - https://github.com/torvalds/linux/blob/master/include/uapi/linux/btrfs_tree.h These files are licensed under the GPL-2.0 WITH Linux-syscall-note, so it should be compatible with the Apache License 2.0. https://spdx.org/licenses/Linux-syscall-note.html The dependency on the kernel headers only affects users building from source. Users on older kernels may opt to not compile this library (`BUILDTAGS=no_btfs`), or to provide headers from a newer kernel. Signed-off-by: Akihiro Suda <akihiro.suda.cz@hco.ntt.co.jp>
