2023-10-22bcachefs: btree_bkey_cached_commonKent Overstreet
This is prep work for the btree key cache: btree iterators will point to either struct btree, or a new struct bkey_cached. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2023-10-22bcachefs: Avoid write lock on mark_lockKent Overstreet
mark_lock is a frequently taken lock, and there's also potential for deadlocks since currently bch2_clear_page_bits which is called from memory reclaim has to take it to drop disk reservations. The disk reservation get path takes it when it recalculates the number of sectors known to be available, but it's not really needed for consistency. We just want to make sure we only have one thread updating the sectors_available count, which we can do with a dedicated mutex. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-22bcachefs: Fix a bug with multiple iterators being traversedKent Overstreet
If upgrade fails on one iterator, but it was copied from another iterator and will be freed before transaction restart, then the original iterator will get traversed first, so we need to make required btree nodes on the original iterator will be traversed too.

2023-10-22bcachefs: Fix hang while shutting downKent Overstreet
If the allocator thread exited before bch2_dev_allocator_stop() was called (because of an error), bch2_dev_allocator_quiesce() could hang. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2023-10-22bcachefs: Rewrite journal_seq_blacklist machineryKent Overstreet
Now, we store blacklisted journal sequence numbers in the superblock, not the journal: this helps to greatly simplify the code, and more importantly it's now implemented in a way that doesn't require all btree nodes to be visited before starting the journal - instead, we unconditionally blacklist the next 4 journal sequence numbers after an unclean shutdown.
