btrfs-fuse

This is a read-only btrfs implementation using FUSE (Filesystem in Userspace). Although btrfs is already in mainline Linux kernel, there are still use-cases for such read-only btrfs implementation: - Educational purpose: let new developers get a quick way to learn how a complex and modern filesystem works; - For certain bootloaders: certain bootloaders need code base compatible with their license; - As a last resort method for subpage/multipage support: currently (v5.16-rc) the Linux kernel can only support sectorsize == pagesize , and 4K sectorsize with 64K page size; thus this project can act as a last resort method to read data from filesystem with unsupported sectorsize.
