2024-01-01	bcachefs: Rename bch_replicas_entry -> bch_replicas_entry_v1	Kent Overstreet	1	-1/+1
	Prep work for introducing bch_replicas_entry_v2 Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23	bcachefs: Simplify ec stripes heap	Kent Overstreet	1	-5/+0
	Now that we have a separate data structure for tracking open stripes, the stripes heap can track all existing stripes, which is a nice simplification. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

2023-10-23	bcachefs: Split out struct gc_stripe from struct stripe	Kent Overstreet	1	-0/+9
	We have two radix trees of stripes - one that mirrors some information from the stripes btree in normal operation, and another that GC uses to recalculate block usage counts. The normal one is now only used for finding partially empty stripes in order to reuse them - the normal stripes radix tree and the GC stripes radix tree are used significantly differently, so this patch splits them into separate types. In an upcoming patch we'll be replacing c->stripes with a btree that indexes stripes by the order we want to reuse them. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
2023-10-23	bcachefs: Have fsck check for stripe pointers matching stripe	Kent Overstreet	1	-0/+1

2023-10-23	bcachefs: Kill stripe->dirty	Kent Overstreet	1	-2/+1
	This makes bch2_stripes_write() work more like bch2_alloc_write(). Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23	bcachefs: Add BCH_BKEY_PTRS_MAX	Kent Overstreet	1	-4/+2
	This now means "the maximum number of pointers within a bkey" - and bch_devs_list is updated to use it instead of BCH_REPLICAS_MAX, since stripes can contain more than BCH_REPLICAS_MAX pointers.

2023-10-23	bcachefs: Improve stripe triggers/heap code	Kent Overstreet	1	-0/+1
	Soon we'll be able to modify existing stripes - replacing empty blocks with new blocks and new p/q blocks. This patch updates the trigger code to handle pointers changing in an existing stripe; also, it significantly improves how the stripes heap works, which means we can get rid of the stripe creation/deletion lock.
