* bcachefs: Fix __bch2_btree_and_journal_iter_init_node_iter()Kent Overstreet2024-04-101-5/+7
| | | | | | | We weren't respecting trans->journal_replay_not_finished - we shouldn't be searching the journal keys unless we have a ref on them. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
* bcachefs: Fix gap buffer bug in bch2_journal_key_insert_take()Kent Overstreet2024-04-071-10/+45
| | | | | | | | | | | | | Multiple bug fixes for journal iters: - When the journal keys gap buffer is resized, we have to adjust the iterators for moving the gap to the end - We don't want to rewind iterators to point to the key we just inserted if it's not for the correct btree/level Also, add some new assertions.

* bcachefs: btree_and_journal_iter now respects trans->journal_replay_not_finishedKent Overstreet2024-03-311-5/+8
| | | | | | | btree_and_journal_iter is now safe to use at runtime, not just during recovery before journal keys have been freed. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
* bcachefs: split out ignore_blacklisted, ignore_not_dirtyKent Overstreet2024-03-131-1/+1

* bcachefs: journal_keys now uses darray helpersKent Overstreet2024-03-131-55/+23
| | | | | | nice bit of code cleanup Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
* bcachefs: Rename journal_keys.d -> journal_keys.dataKent Overstreet2024-03-131-34/+34
| | | | | | This will let us use some darray helpers in the next patch. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

* bcachefs: btree node prefetching in check_topologyKent Overstreet2024-03-101-0/+31
| | | | | | | | | | btree_and_journal_iter is old code that we want to get rid of, but we're not ready to yet. lack of btree node prefetching is, it turns out, a real performance issue for fsck on spinning rust, so - add it. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
* bcachefs: btree_and_journal_iter.transKent Overstreet2024-03-101-7/+8
| | | | | | | we now always have a btree_trans when using a btree_and_journal_iter; prep work for adding prefetching to btree_and_journal_iter Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

* bcachefs: convert bch_fs_flags to x-macroKent Overstreet2024-01-011-1/+1
| | | | | | | Now we can print out filesystem flags in sysfs, useful for debugging various "what's my filesystem doing" issues. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
* bcachefs: Kill btree_iter->journal_posKent Overstreet2024-01-011-2/+17
| | | | | | | | | | | | | For BTREE_ITER_WITH_JOURNAL, we memoize lookups in the journal keys, to avoid the binary search overhead. Previously we stashed the pos of the last key returned from the journal, in order to force the lookup to be redone when rewinding. Now bch2_journal_keys_peek_upto() handles rewinding itself when necessary - so we can slim down btree_iter. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
* bcachefs: Proper refcounting for journal_keysKent Overstreet2023-11-241-3/+15
| | | | | | | | | The btree iterator code overlays keys from the journal until journal replay is finished; since we're now starting copygc/rebalance etc. before replay is finished, this is multithreaded access and thus needs refcounting. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
* bcachefs: btree_journal_iter.cKent Overstreet2023-10-221-0/+531
Split out a new file from recovery.c for managing the list of keys we read from the journal: before journal replay finishes the btree iterator code needs to be able to iterate over and return keys from the journal as well, so there's a fair bit of code here.
