2025-09-29Remove bcachefs core codeLinus Torvalds1-144/+0
bcachefs was marked 'externally maintained' in 6.17 but the code remained to make the transition smoother. It's now a DKMS module, making the in-kernel code stale, so remove it to avoid any version confusion.

2025-05-21bcachefs: enumerated_ref.cKent Overstreet1-0/+144
Factor out the debug code for rw filesystem refs into a small library. In release mode an enumerated ref is a normal percpu refcount, but in debug mode all enumerated users of the ref get their own atomic_long_t ref - making it much easier to chase down refcount usage bugs for when a refcount has many users. For debugging, we have enumerated_ref_to_text(), which prints the current value of each different user. Additionally, in debug mode enumerated_ref_stop() has a 10 second timeout, after which it will dump outstanding refcounts. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
