baabeb49 - bcachefs: Factor out progress.[ch]

Thu, 06 Feb 2025 20:59:28 +0000

bcachefs: Factor out progress.[ch]the backpointers code has progress indicators; these aren't great, sincethey print to the dmesg console and we much prefer to have progressindicators reporting to a specific userspace program so they're notspamming the system console.But not all codepaths that need progress indicators support that yet,and we don't want users to think "this is hung".Signed-off-by: Kent Overstreet List of files: /linux-6.15/fs/bcachefs/Makefile

8e973a4f - bcachefs: rcu_pending

Tue, 11 Jun 2024 00:47:03 +0000

bcachefs: rcu_pendingGeneric data structure for explicitly tracking pending RCU items,allowing items to be dequeued (i.e. allocate from items pendingfreeing). Works with conventional RCU and SRCU, and possibly other RCUflavors in the future, meaning this can serve as a more genericreplacement for SLAB_TYPESAFE_BY_RCU.Pending items are tracked in radix trees; if memory allocation fails, wefall back to linked lists.A rcu_pending is initialized with a callback, which is invoked whenpending items's grace periods have expired. Two types of callbackprocessing are handled specially:- RCU_PENDING_KVFREE_FN New backend for kvfree_rcu(). Slightly faster, and eliminates the synchronize_rcu() slowpath in kvfree_rcu_mightsleep() - instead, an rcu_head is allocated if we don't have one and can't use the radix tree TODO: - add a shrinker (as in the existing kvfree_rcu implementation) so that memory reclaim can free expired objects if callback processing isn't keeping up, and to expedite a grace period if we're under memory pressure and too much memory is stranded by RCU - add a counter for amount of memory pending- RCU_PENDING_CALL_RCU_FN Accelerated backend for call_rcu() - pending callbacks are tracked in a radix tree to eliminate linked list overhead.to serve as replacement backends for kvfree_rcu() and call_rcu(); thesemay be of interest to other uses (e.g. SLAB_TYPESAFE_BY_RCU users).Note:Internally, we're using a single rearming call_rcu() callback fornotifications from the core RCU subsystem for notifications when objectsare ready to be processed.Ideally we would be getting a callback every time a grace periodcompletes for which we have objects, but that would require multiplercu_heads in flight, and since the number of gp sequence numbers withuncompleted callbacks is not bounded, we can't do that yet.Signed-off-by: Kent Overstreet List of files: /linux-6.15/fs/bcachefs/Makefile

2744e5c9 - bcachefs: KEY_TYPE_accounting

Wed, 27 Dec 2023 23:31:46 +0000

bcachefs: KEY_TYPE_accountingNew key type for the disk space accounting rewrite. - Holds a variable sized array of u64s (may be more than one for accounting e.g. compressed and uncompressed size, or buckets and sectors for a given data type) - Updates are deltas, not new versions of the key: this means updates to accounting can happen via the btree write buffer, which we'll be teaching to accumulate deltas.Signed-off-by: Kent Overstreet List of files: /linux-6.15/fs/bcachefs/Makefile

4409b808 - bcachefs: Repair pass for scanning for btree nodes

Tue, 12 Mar 2024 03:11:46 +0000

bcachefs: Repair pass for scanning for btree nodesIf a btree root or interior btree node goes bad, we're going to lose alot of data, unless we can recover the nodes that it pointed to byscanning.Fortunately btree node headers are fully self describing, andadditionally the magic number is xored with the filesytem UUID, so wecan do so safely.This implements the scanning - next patch will rework topology repair tomake use of the found nodes.Signed-off-by: Kent Overstreet List of files: /linux-6.15/fs/bcachefs/Makefile

d2554263 - bcachefs: Split out recovery_passes.c

Sun, 24 Mar 2024 00:07:46 +0000

bcachefs: Split out recovery_passes.cWe've grown a fair amount of code for managing recovery passes; trackingwhich ones we're running, which ones need to be run, and flagging in thesuperblock which ones need to be run on the next recovery.So it's worth splitting out into its own file, this code is prettydifferent from the code in recovery.c.Signed-off-by: Kent Overstreet List of files: /linux-6.15/fs/bcachefs/Makefile

Fri, 29 Dec 2023 20:25:07 +0000

bcachefs: bch_sb_field_downgradeAdd a new superblock section that contains a list of { minor version, recovery passes, errors_to_fix }that is - a list of recovery passes that must be run when downgradingpast a given version, and a list of errors to silently fix.The upcoming disk accounting rewrite is not going to be fullycompatible: we're going to have to regenerate accounting both whenupgrading to the new version, and also from downgrading from the newversion, since the new method of doing disk space accounting is acompletely different architecture based on deltas, and synchronizingthem for every jounal entry write to maintain compatibility is going tobe too expensive and impractical.Signed-off-by: Kent Overstreet List of files: /linux-6.15/fs/bcachefs/Makefile
