2023-10-23	bcachefs: Array bounds fixes	Kent Overstreet	1	-3/+13
	It's no longer legal to use a zero size array as a flexible array member - this causes UBSAN to complain. This patch switches our zero size arrays to normal flexible array members when possible, and inserts casts in other places (e.g. where we use the zero size array as a marker partway through an array).

2023-10-23	bcachefs: Kill bch2_sort_repack_merge()	Kent Overstreet	1	-5/+0
	The main function of bch2_sort_repack_merge() was to call .key_normalize on every key, which drops stale (cached) pointers - it hasn't actually merged extents in quite some time. But bch2_gc_gens() now works on individual keys - we used to gc old gens by rewriting entire btree nodes. With that gone, there's no need for internal btree code to be calling .key_normalize anymore.

2023-10-23	bcachefs: Kill support for !BTREE_NODE_NEW_EXTENT_OVERWRITE()	Kent Overstreet	1	-8/+0
	bcachefs has been aggressively migrating filesystems and btree nodes to the new format for quite some time - this shouldn't affect anyone anymore, and lets us delete a _lot_ of code. Also, it frees up KEY_TYPE_discard for a new whiteout key type for snapshots. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23	bcachefs: Kill btree_node_iter_large	Kent Overstreet	1	-18/+8
	Long overdue cleanup - this converts btree_node_iter_large uses to sort_iter. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23	bcachefs: Refactor whiteouts compaction	Kent Overstreet	1	-2/+0
	The whiteout compaction path - as opposed to just dropping whiteouts - is now only needed for extents, and soon will only be needed for extent btree nodes in the old format. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23	bcachefs: Make bkey types globally unique	Kent Overstreet	1	-4/+5
	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>
