Hi Linus - another opossum for the posse: The following changes since commit 0c3836482481200ead7b416ca80c68a29cfdaabd: Linux 6.10 (2024-07-14 15:43:32 -0700) are available in the Git repository at: https://evilpiepirate.org/git/bcachefs.git tags/bcachefs-2024-07-14 for you to fetch changes up to efb2018e4d238cc205690ac62c0917d60d291e66: bcachefs: Kill bch2_assert_btree_nodes_not_locked() (2024-07-14 19:59:12 -0400) ---------------------------------------------------------------- bcachefs changes for 6.11-rc1 - Metadata version 1.8: Stripe sectors accounting, BCH_DATA_unstriped This splits out the accounting of dirty sectors and stripe sectors in alloc keys; this lets us see stripe buckets that still have unstriped data in them. This is needed for ensuring that erasure coding is working correctly, as well as completing stripe creation after a crash. - Metadata version 1.9: Disk accounting rewrite The previous disk accounting scheme relied heavily on percpu counters that were also sharded by outstanding journal buffer; it was fast but not extensible or scalable, and meant that all accounting counters were recorded in every journal entry. The new disk accounting scheme stores accounting as normal btree keys; updates are deltas until they are flushed by the btree write buffer. This means we have no practical limit on the number of counters, and a new tagged union format that's easy to extend. We now have counters for compression type/ratio, per-snapshot-id usage, per-btree-id usage, and pending rebalance work. - Self healing on read IO/checksum error data is now automatically rewritten if we get a read error and then a successful retry - Mount API conversion (thanks to Thomas Bertschinger) - Better lockdep coverage Previously, btree node locks were tracked individually by lockdep, like any other lock. But we may take _many_ btree node locks simultaneously, we easily blow through the limit of 48 locks that lockdep can track, leading to lockdep turning itself off. Tracking each btree node lock individually isn't really necessary since we have our own cycle detector for deadlock avoidance and centralized tracking of btree node locks, so we now have a single lockdep_map in btree_trans for "any btree nodes are locked". - some more small incremental work towards online check_allocations - lots more debugging improvements, fixes
