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: Don't set BCH_FS_error on transaction restart

2025-07-08T19:24:15Z

This started showing up more when we started logging the error being corrected in the journal - but __bch2_fsck_err() could return transaction restarts before that. Setting BCH_FS_error incorrectly causes recovery passes to not be cleared, among other issues. Fixes: b43f72492768 ("bcachefs: Log fsck errors in the journal") Signed-off-by: Kent Overstreet

bcachefs: btree read retry fixes

2025-07-05T16:42:41Z

Fix btree node read retries after validate errors: __btree_err() is the wrong place to flag a topology error: that is done by btree_lost_data(). Additionally, some calls to bch2_bkey_pick_read_device() were not updated in the 6.16 rework for improved log messages; we were failing to signal that we still had a retry.

bcachefs: Don't log fsck err in the journal if doing repair elsewhere

2025-06-19T17:08:07Z

This fixes exceeding the bump allocator limit when the allocator finds many buckets that need repair - they're repaired asynchronously, which means that every error logged a message in the bump allocator, without committing. Signed-off-by: Kent Overstreet

bcachefs: Fix possible console lock involved deadlock

bcachefs: Log fsck errors in the journal

2025-06-12T03:21:29Z

Log the specific error being corrected in the journal when we're repairing, this helps greatly with 'bcachefs list_journal' analysis. Signed-off-by: Kent Overstreet

bcachefs: bch_err_throw()

2025-06-02T16:16:35Z

Add a tracepoint for any time we return an error and unwind. Signed-off-by: Kent Overstreet

bcachefs: Use bch2_err_matches() for BCH_ERR_fsck_(fix|ignore)

2025-06-01T02:03:16Z

We'll be adding subtypes of these errors, and new error code tracing. Signed-off-by: Kent Overstreet

bcachefs: bch2_inum_snapshot_to_path()

2025-05-22T00:15:09Z

Add a better helper for printing out paths of inodes when we don't know the subvolume, for fsck. Signed-off-by: Kent Overstreet

bcachefs: bch2_run_explicit_recovery_pass() cleanup

2025-05-22T00:15:04Z

Consolidate the run_explicit_recovery_pass() interfaces by adding a flags parameter; this will also let us add a RUN_RECOVERY_PASS_ratelimit flag. Signed-off-by: Kent Overstreet
