Remove bcachefs core code

2025-09-29T20:43:52+00:00

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: Fix write buffer flushing from open journal entry

2025-07-25T02:56:37+00:00

When flushing the btree write buffer, we pull write buffer keys directly from the journal instead of letting the journal write path copy them to the write buffer. When flushing from the currently open journal buffer, we have to block new reservations and wait for outstanding reservations to complete. Recheck the reservation state after blocking new reservations: previously, we were checking the reservation count from before calling __journal_block(). Signed-off-by: Kent Overstreet

bcachefs: Use wait_on_allocator() when allocating journal

2025-06-24T22:16:01+00:00

wait_on_allocator() emits debug info when we hang trying to allocate. Signed-off-by: Kent Overstreet

bcachefs: pass last_seq into fs_journal_start()

2025-06-16T02:11:56+00:00

Prep work for journal rewind, where the seq we're replaying from may be different than the last journal entry's last_seq. Signed-off-by: Kent Overstreet

bcachefs: bch_err_throw()

2025-06-02T16:16:35+00:00

Add a tracepoint for any time we return an error and unwind. Signed-off-by: Kent Overstreet

bcachefs: Replace rcu_read_lock() with guards

2025-06-01T04:03:12+00:00

The new guard(), scoped_guard() allow for more natural code. Some of the uses with creative flow control have been left. Signed-off-by: Kent Overstreet

bcachefs: bch2_dev_journal_bucket_delete()

2025-06-01T02:03:17+00:00

Recover from "journal and btree in same bucket". Signed-off-by: Kent Overstreet

bcachefs: Ensure we don't use a blacklisted journal seq

2025-05-23T23:52:31+00:00

Different versions differ on the size of the blacklist range; it is theoretically possible that we could end up with blacklisted journal sequence numbers newer than the newest seq we find in the journal, and pick a new start seq that's blacklisted. Explicitly check for this in bch2_fs_journal_start(). Signed-off-by: Kent Overstreet

bcachefs: bch_dev.io_ref -> enumerated_ref

2025-05-22T00:14:28+00:00

Convert device IO refs to enumerated_refs, for easier debugging of refcount issues. Simple conversion: enumerate all users and convert to the new helpers. Signed-off-by: Kent Overstreet

bcachefs: bch_fs.writes -> enumerated_refs

2025-05-22T00:14:27+00:00

Drop the single-purpose write ref code in bcachefs.h, and convert to enumarated refs. Signed-off-by: Kent Overstreet
