Remove bcachefs core code

2025-09-29T20:43:52Z

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.

fs: replace use of system_unbound_wq with system_dfl_wq

2025-09-19T14:15:07Z

Currently if a user enqueue a work item using schedule_delayed_work() the used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to schedule_work() that is using system_wq and queue_work(), that makes use again of WORK_CPU_UNBOUND. This lack of consistentcy cannot be addressed without refactoring the API. system_unbound_wq should be the default workqueue so as not to enforce locality constraints for random work whenever it's not required. Adding system_dfl_wq to encourage its use when unbound work should be used. The old system_unbound_wq will be kept for a few release cycles.

bcachefs: bch_fs.writes -> enumerated_refs

2025-05-22T00:14:27Z

Drop the single-purpose write ref code in bcachefs.h, and convert to enumarated refs. Signed-off-by: Kent Overstreet

bcachefs: Move various init code to _init_early()

2025-05-22T00:14:02Z

_init_early() is for initialization that cannot fail, and often must happen for teardown partway through initialization to work. Signed-off-by: Kent Overstreet

bcachefs: Use sort_nonatomic() instead of sort()

2025-04-06T23:33:53Z

Fixes "task out to lunch" warnings during recovery on large machines with lots of dirty data in the journal. Signed-off-by: Kent Overstreet

bcachefs: Kill btree_iter.trans

2025-04-02T14:24:34Z

This was planned to be done ages ago, now finally completed; there are places where we have quite a few btree_trans objects on the stack, so this reduces stack usage somewhat. Signed-off-by: Kent Overstreet
