* bcachefs: Kill direct access to bi_io_vecKent Overstreet2023-10-221-10/+6

* bcachefs: Rewrite journal_seq_blacklist machineryKent Overstreet2023-10-221-0/+1
| | | | | | | | | | | 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.

* bcachefs: Make bkey types globally uniqueKent Overstreet2023-10-221-22/+29
| | | | | | | | | | this lets us get rid of a lot of extra switch statements - in a lot of places we dispatch on the btree node type, and then the key type, so this is a nice cleanup across a lot of code. Also improve the on disk format versioning stuff. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

* bcachefs: Assorted fixes for running on very small devicesKent Overstreet2023-10-221-1/+1
| | | | | | | | It's now possible to create and use a filesystem on a 512k device with 4k buckets (though at that size we still waste almost half to internal reserves) Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
