* bcachefs: Convert gc to new accountingKent Overstreet2024-07-141-1/+0
| | | | | | | | | | Rewrite fsck/gc for the new accounting scheme. This adds a second set of in-memory accounting counters for gc to use; like with other parts of gc we run all trigger in TRIGGER_GC mode, then compare what we calculated to existing in-memory accounting at the end.

* bcachefs: Delete journal-buf-sharded old style accountingKent Overstreet2024-07-141-4/+0

* bcachefs: Disk space accounting rewriteKent Overstreet2024-07-141-8/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Main part of the disk accounting rewrite. This is a wholesale rewrite of the existing disk space accounting, which relies on percepu counters that are sharded by journal buffer, and rolled up and added to each journal write. With the new scheme, every set of counters is a distinct key in the accounting btree; this fixes scaling limitations of the old scheme, where counters took up space in each journal entry and required multiple percpu counters. Now, in memory accounting requires a single set of percpu counters - not multiple for each in flight journal buffer - and in the future we'll probably also have counters that don't use in memory percpu counters, they're not strictly required. An accounting update is now a normal btree update, using the btree write buffer path. At transaction commit time, we apply accounting updates to the in memory counters, which are percpu counters indexed in an eytzinger tree by the accounting key.

* bcachefs: Rename bch_replicas_entry -> bch_replicas_entry_v1Kent Overstreet2024-01-011-11/+11
| | | | | | Prep work for introducing bch_replicas_entry_v2 Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
* bcachefs: Add missing validation for jset_entry_data_usageKent Overstreet2023-11-281-0/+2
| | | | | | | | Validation was completely missing for replicas entries in the journal (not the superblock replicas section) - we can't have replicas entries pointing to invalid devices. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
* bcachefs: Fix bch2_trans_reset_updates()Kent Overstreet2023-10-221-16/+0
| | | | | | This should have been resetting trans->fs_usage_deltas as well. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
* bcachefs: Move bkey bkey_unpack_key() to bkey.hKent Overstreet2023-10-221-0/+1
| | | | | | | | | | Long ago, bkey_unpack_key() was added to bset.h instead of bkey.h because bkey.h didn't include btree_types.h, which it needs for the compiled unpack function. This patch finally moves it to the proper location. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
* bcachefs: Add .to_text() methods for all superblock sectionsKent Overstreet2023-10-221-0/+1
| | | | | | | | | This patch improves the superblock .to_text() methods and adds methods for all types that were missing them. It also improves printbufs by allowing them to specfiy what units we want to be printing in, and adds new wrapper methods for unifying our kernel and userspace environments.

* bcachefs: Handle replica marking fsck errors locallyKent Overstreet2023-10-221-2/+0
| | | | | | | | This simplifies the code quite a bit and eliminates an inconsistency - a given bkey doesn't necessarily translate to a single replicas entry for disk space accounting. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com>
* bcachefs: Kill bch2_replicas_delta_list_marked()Kent Overstreet2023-10-221-1/+0
| | | | | | | | | This changes bch2_trans_fs_usage_apply() to handle failure (replicas entry missing) by reverting the changes it made - meaning we can make the main transaction commit path a bit slimmer, and perhaps also simplify some locking in upcoming patches.

* bcachefs: Kill bch2_fs_usage_scratch_get()Kent Overstreet2023-10-221-0/+25
| | | | | | | | This is an important cleanup, eliminating an unnecessary copy in the transaction commit path. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

* bcachefs: Redo checks for sufficient devicesKent Overstreet2023-10-221-13/+3
| | | | | | | | | When the replicas mechanism was added, for tracking data by which drives it's replicated on, the check for whether we have sufficient devices was never updated to make use of it. This patch finally does that. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
* bcachefs: Add missing call to bch2_replicas_entry_sort()Kent Overstreet2023-10-221-0/+1
| | | | | | | | | This fixes a bug introduced by "bcachefs: Improve diagnostics when journal entries are missing" - devices in a replicas entry are supposed to be sorted. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
* bcachefs: Refactor replicas codeKent Overstreet2023-10-221-6/+2
| | | | | | | | | | | | | | Awhile back the mechanism for garbage collecting unused replicas entries was significantly improved, but some cleanup was missed - this patch does that now. This is also prep work for a patch to account for erasure coded parity blocks separately - we need to consolidate the logic for checking/marking the various replicas entries from one bkey into a single function.

* bcachefs: Redo filesystem usage ioctlsKent Overstreet2023-10-221-3/+0
| | | | | | | | | | | When disk space accounting was changed to be tracked by replicas entry, the ioctl interface was never update: this patch finally does that. Aditionally, the BCH_IOCTL_USAGE ioctl is now broken out into separate ioctls for filesystem and device usage.

* bcachefs: Make bkey types globally uniqueKent Overstreet2023-10-221-3/+2
| | | | | | | | | | 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>
