2023-10-23bcachefs: Add .to_text() methods for all superblock sectionsKent Overstreet1-0/+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.

2023-10-23bcachefs: Handle replica marking fsck errors locallyKent Overstreet1-2/+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>
2023-10-23bcachefs: Kill bch2_replicas_delta_list_marked()Kent Overstreet1-1/+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.

2023-10-23bcachefs: Kill bch2_fs_usage_scratch_get()Kent Overstreet1-0/+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>

2023-10-23bcachefs: Redo checks for sufficient devicesKent Overstreet1-13/+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>
2023-10-23bcachefs: Add missing call to bch2_replicas_entry_sort()Kent Overstreet1-0/+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>
2023-10-23bcachefs: Refactor replicas codeKent Overstreet1-6/+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.

2023-10-23bcachefs: Redo filesystem usage ioctlsKent Overstreet1-3/+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.

2023-10-23bcachefs: Make bkey types globally uniqueKent Overstreet1-3/+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>
