bcachefs: Initial commit Initially forked from drivers/md/bcache, bcachefs is a new copy-on-write filesystem with every feature you could possibly want. Website: https://bcachefs.org Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

bcachefs: Add persistent counters This adds a new superblock field for persisting counters and adds a sysfs interface in counters/ exposing these counters. The superblock field is ignored by older versions letting us avoid an on disk version bump. Each sysfs file outputs a counter that tracks since filesystem creation and a counter for the current mount session.
