A new bcachefs release

Kent Overstreet has announced a new major release of his bcachefs filesystem. Changes in this release include whole-filesystem encryption, backup superblocks, better multiple-device support, a user-space filesystem checker, and more. "We can also now migrate filesystems to bcachefs in place! The bcache migrate command takes an existing filesystem, fallocates a big file in it, creates a new filesystem (in userspace) on the block device but using only the space reserved by that file it fallocated - and then walks the contents of the original filesystem creating pointers to all your existing data." There is an on-disk format change, but there's a chance it's the last one.
