2025-05-21bcachefs: __bch2_run_recovery_passes()Kent Overstreet
Consolidate bch2_run_recovery_passes() and bch2_run_online_recovery_passes(), prep work for automatically scheduling and running recovery passes in the background. - Now takes a mask of which passes to run, automatic background repair will pass in sb.recovery_passes_required. - Skips passes that are failing: a pass that failed may be reattempted after another pass succeeds (some passes depend on repair done by other passes for successful completion). - bch2_recovery_passes_match() helper to skip alloc passes on a filesystem without alloc info.

2025-05-21bcachefs: struct bch_fs_recoveryKent Overstreet
bch_fs has gotten obnoxiously big, let's start organizing thins a bit better. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2025-05-21bcachefs: do_rebalance_scan() now only updates bch_extent_rebalanceKent Overstreet
This ensures that our pending rebalance work accounting is accurate quickly. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-05-21bcachefs: better error message for subvol_fs_path_parent_wrongKent Overstreet
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-05-21bcachefs: Improve bch2_repair_inode_hash_info()Kent Overstreet
Improve this so it can be used by fsck.c check_inode(); it provides a much better error message than the check_inode() version. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-05-21bcachefs: bch2_inode_find_snapshot_root()Kent Overstreet
Factor out a small common helper. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2025-05-21bcachefs: Fix opt hooks in sysfs for non sb optionKent Overstreet
We weren't checking if the option changed for non-superblock options - this led to rebalance not waking up when enabling the "rebalance_enabled" option. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-05-21bcachefs: fix can_write_extent()Kent Overstreet
Failing to check the return value of bch2_dev_rcu(): we could (technically) race with device removal. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-05-21bcachefs: Add tracepoint, counter for io_move_created_rebalanceKent Overstreet
Internal moves shouldn't add new rebalance_work, but it's been reported that this seems to be happening. Add a tracepoint and counter so we can see what's going on. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-05-21bcachefs: move_buckets in rhashtable when allocatedKent Overstreet

Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-05-21bcachefs: kill move_bucket_in_flightKent Overstreet
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 <kent.overstreet@linux.dev>
2025-05-21bcachefs: bch2_fs_emergency_read_only2()Kent Overstreet
More error message cleanup: instead of multiple printk()s per error, we want to be building up a single error message in a printbuf, so that it can be printed with indenting that shows grouping and avoid errors getting interspersed or lost in the log. This gets rid of most calls to bch2_fs_emergency_read_only(). We still have calls to - bch2_fatal_error() - bch2_fs_fatal_error() - bch2_fs_fatal_err_on() that need work.

2025-05-21bcachefs: debug_check_btree_locking modparamKent Overstreet
Don't put btree locking asserts behind CONFIG_BCACHEFS_DEBUG, put them behind a module parameter. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-05-21bcachefs: Debug params are now static_keysKent Overstreet
We'd like users to be able to debug without building custom kernels, so this will help us get rid of CONFIG_BCACHEFS_DEBUG, at least for most things. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2025-05-21bcachefs: bch_sb_field_recovery_passesKent Overstreet
New superblock section for statistics on recovery passes - last time ran (successfully), last runtime. This will be used by self healing code to determine when to kick off potentially expensive recovery passes. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2025-05-21bcachefs: "buckets with backpointer mismatches" now allocated on demandKent Overstreet
More self healing work: we're going to be calling check_bucket_backpointer_mismatch() at runtime, outside of fsck. Then when we need to we'll kick off the full check_extents_to_backpointers recovery pass. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2025-05-21bcachefs: buckets_in_flight on stackKent Overstreet
copygc runs with a full stack available, there's no reason to dynamically allocate this. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-05-21bcachefs: bch2_copygc_dev_wait_amount()Kent Overstreet

2025-05-21bcachefs: Knob for manual snapshot deletionKent Overstreet
Add 'opts.snapshot_deletion_enabled', enabled by default. This may be turned off so that the new sysfs knob, 'internal/trigger_delete_dead_snapshots', may be used instead - this will allow snapshot deletion to be profiled more easily. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-05-21bcachefs: bcachefs_metadata_version_fast_device_removalKent Overstreet
Fast device removal, that uses backpointers to find pointers to the device being removed instead of a full metadata scan. This requires BCH_SB_MEMBER_DELETED_UUID, which is an incompatible change - hence the version number bump. We don't fully trust backpointers, so we don't want to reuse device indexes until after a fsck has verified that there aren't any pointers to removed devices. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-05-21bcachefs: bch2_dev_data_drop_by_backpointers()Kent Overstreet
Currently, device removal has to scan all metadata for pointers to the device being removed. Add a new method, with the same interface as bch2_dev_data_drop(), that scans by backpointers instead - this will drastically speed up device removal. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2025-05-21bcachefs: BCH_SB_MEMBER_DELETED_UUIDKent Overstreet
Add a sentinal value for devices that have been removed, but don't want to reuse their index until a fsck has completed. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2025-05-21bcachefs: inline bch2_ob_ptr()Kent Overstreet
This was an oversight, we want bch2_alloc_sectors_append_ptrs_inlined() fully inlined. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
