2024-01-01bcachefs: trans_for_each_update() now declares loop iterKent Overstreet1-1/+1
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-01-01bcachefs: kill btree_trans->wb_updatesKent Overstreet1-59/+3
the btree write buffer path now creates a journal entry directly Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-01-01bcachefs: Improve trans->extra_journal_entriesKent Overstreet1-36/+56
Instead of using a darray, we now allocate journal entries for the transaction commit path with our normal bump allocator - with an inlined fastpath, and using btree_transaction_stats to remember how much to initially allocate so as to avoid transaction restarts. This is prep work for converting write buffer updates to use this mechanism. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-01-01bcachefs: No need to allocate keys for write bufferKent Overstreet1-25/+5
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-01-01bcachefs: Rename BTREE_INSERT flagsKent Overstreet1-2/+2
BTREE_INSERT flags are actually transaction commit flags - rename them for clarity. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-01-01bcachefs: Kill BTREE_UPDATE_PREJOURNALKent Overstreet1-23/+0
With the previous patch that reworks BTREE_INSERT_JOURNAL_REPLAY, we can now switch the btree write buffer to use it for flushing. This has the advantage that transaction commits don't need to take a journal reservation at all. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-12-22bcachefs: Fix insufficient disk reservation with compression + snapshotsKent Overstreet1-7/+8
When overwriting and splitting existing extents, we weren't correctly accounting for a 3 way split of a compressed extent. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-12-04bcachefs; Don't use btree write buffer until journal replay is finishedKent Overstreet1-0/+16
The keys being replayed by journal replay have to be synchronized with updates by other threads that overwrite them. We rely on btree node locks for synchronizing - but since btree write buffer updates take no btree locks, that won't work. Instead, simply disable using the btree write buffer until journal replay is finished. This fixes a rare backpointers error in the merge_torture_flakey test.

2023-10-23bcachefs: More minor smatch fixesKent Overstreet1-1/+1
- fix a few uninitialized return values - return a proper error code in lookup_lostfound() Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Heap allocate btree_transKent Overstreet1-3/+3
We're using more stack than we'd like in a number of functions, and btree_trans is the biggest object that we stack allocate. But we have to do a heap allocatation to initialize it anyways, so there's no real downside to heap allocating the entire thing. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Fix W=12 build errorsKent Overstreet1-7/+13
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: BTREE_ID_logged_opsKent Overstreet1-0/+18
Add a new btree for long running logged operations - i.e. for logging operations that we can't do within a single btree transaction, so that they can be resumed if we crash. Keys in the logged operations btree will represent operations in progress, with the state of the operation stored in the value. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: bch2_trans_update_get_key_cache()Kent Overstreet1-29/+42
Factor out a slowpath into a separate function. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Fix bch2_propagate_key_to_snapshot_leaves()Kent Overstreet1-3/+1
When we handle a transaction restart in a nested context, we need to return -BCH_ERR_transaction_restart_nested because we invalidated the outer context's iterators and locks. bch2_propagate_key_to_snapshot_leaves() wasn't doing this, this patch fixes it to use trans_was_restarted().

2023-10-23bcachefs: move check_pos_snapshot_overwritten() to snapshot.cKent Overstreet1-49/+4
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: Split out snapshot.cKent Overstreet1-1/+1
subvolume.c has gotten a bit large, this splits out a separate file just for managing snapshot trees - BTREE_ID_snapshots. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2023-10-23bcachefs: btree_journal_iter.cKent Overstreet1-1/+1
Split out a new file from recovery.c for managing the list of keys we read from the journal: before journal replay finishes the btree iterator code needs to be able to iterate over and return keys from the journal as well, so there's a fair bit of code here.

2023-10-23bcachefs: Split up btree_update_leaf.cKent Overstreet1-0/+943
