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.

bcachefs: kill move_bucket_in_flight

2025-05-22T00:14:57Z

Small cleanup/simplification, and prep work for the next patch, which will add checking if buckets don't get evacuated because they're missing backpointers. Signed-off-by: Kent Overstreet

bcachefs: Eliminate padding in move_bucket_key

2025-03-24T13:50:37Z

We appear to be tripping over a compiler/kmsan bug with padding fields - this is an easy workaround. Signed-off-by: Kent Overstreet

bcachefs: Scrub

2025-03-15T01:02:12Z

Add a new data op to walk all data and metadata in a filesystem, checking if it can be read successfully, and on error repairing from another copy if possible. - New helper: bch2_dev_idx_is_online(), so that we can bail out and report to userspace when we're unable to scrub because the device is offline - data_update_opts, which controls the data move path, now understands scrub: data is only read, not written. The read path is responsible for rewriting on read error, as with other reads. - scrub_pred skips data extents that don't have checksums - bch_ioctl_data has a new scrub member, which has a data_types field for data types to check - i.e. all data types, or only metadata. - Add new entries to bch_move_stats so that we can report numbers for corrected and uncorrected errors - Add a new enum to bch_ioctl_data_event for explicitly reporting completion and return code (i.e. device offline) Signed-off-by: Kent Overstreet

bcachefs: bch2_move_data_phys()

2025-03-15T01:02:12Z

Add a more general version of bch2_evacuate_bucket - to be used for scrub. Signed-off-by: Kent Overstreet

bcachefs: move: move_stats refactoring

2023-10-31T16:18:38Z

data_progress_list is gone - it was redundant with moving_context_list The upcoming rebalance rewrite is going to have it using two different move_stats objects with the same moving_context, depending on whether it's scanning or using the rebalance_work btree - this patch plumbs stats around a bit differently so that will work.

bcachefs: Rhashtable based buckets_in_flight for copygc

2023-10-22T21:09:58Z

Previously, copygc used a fifo for tracking buckets in flight - this had the disadvantage of being fixed size, since we pass references to elements into the move code. This restructures it to be a hash table and linked list, since with erasure coding we need to be able to pipeline across an arbitrary number of buckets. Signed-off-by: Kent Overstreet

bcachefs: Improved copygc pipelining

2023-10-22T21:09:56Z

This improves copygc pipelining across multiple buckets: we now track each in flight bucket we're evacuating, with separate moving_contexts. This means that whereas previously we had to wait for outstanding moves to complete to ensure we didn't try to evacuate the same bucket twice, we can now just check buckets we want to evacuate against the pending list. This also mean we can run the verify_bucket_evacuated() check without killing pipelining - meaning it can now always be enabled, not just on debug builds. This is going to be important for the upcoming erasure coding work, where moving IOs that are being erasure coded will now skip the initial replication step; instead the IOs will wait on the stripe to complete.

bcachefs: add progress stats to sysfs

2023-10-22T21:09:10Z

This adds progress stats to sysfs for copygc, rebalance, recovery, and the cmd_job ioctls. Signed-off-by: Brett Holman Signed-off-by: Kent Overstreet
