Remove bcachefs core code

2025-09-29T20:43:52Z

bcachefs was marked 'externally maintained' in 6.17 but the code remained to make the transition smoother. It's now a DKMS module, making the in-kernel code stale, so remove it to avoid any version confusion.

bcachefs: Separate running/runnable in wp stats

2025-03-15T01:02:11Z

We've got per-writepoint statistics to see how well the writepoint index update threads are pipelining; this separates running vs. runnable so we can see at a glance if they're blocking. Signed-off-by: Kent Overstreet

bcachefs: Fix discard path journal flushing

2025-02-07T03:35:11Z

The discard path is supposed to issue journal flushes when there's too many buckets empty buckets that need a journal commit before they can be written to again, but at some point this code seems to have been lost. Bring it back with a new optimization to make sure we don't issue too many journal flushes: the journal now tracks the sequence number of the most recent flush in progress, which the discard path uses when deciding which buckets need a journal flush.

bcachefs: Allocator prefers not to expand mi.btree_allocated bitmap

2024-05-08T21:29:24Z

We now have a small bitmap in the member info section of the superblock for "regions that have btree nodes", so that if we ever have to scan for btree nodes in repair we don't have to scan the whole device(s). This tweaks the allocator to prefer allocating from regions that are already marked in this bitmap. Signed-off-by: Kent Overstreet

bcachefs: BCH_WATERMARK_interior_updates

2024-04-02T01:14:02Z

This adds a new watermark, higher priority than BCH_WATERMARK_reclaim, for interior btree updates. We've seen a deadlock where journal replay triggers a ton of btree node merges, and these use up all available open buckets and then interior updates get stuck. One cause of this is that we're currently lacking btree node merging on write buffer btrees - that needs to be fixed as well. Signed-off-by: Kent Overstreet

bcachefs: Assorted fixes for clang

2023-10-22T21:10:09Z

clang had a few more warnings about enum conversion, and also didn't like the opts.c initializer. Signed-off-by: Kent Overstreet

bcachefs: Kill JOURNAL_WATERMARK

2023-10-22T21:10:05Z

This unifies JOURNAL_WATERMARK with BCH_WATERMARK; we're working towards specifying watermarks once in the transaction commit path. Signed-off-by: Kent Overstreet

bcachefs: BCH_WATERMARK_reclaim

2023-10-22T21:10:05Z

Add another watermark for journal reclaim - this is needed for the next patches, that unify BCH_WATERMARK with JOURNAL_WATERMARK. Signed-off-by: Kent Overstreet
