Thank you!
Hi Linus, small batch of bcachefs fixes for you. Going to have a larger pull for you soon with some new repair code - some users got hit bad with the failure to downgrade bug (the fix for which is still not in 6.7) - that caused the splitbrain detection to attempt to kick out every device from the filesystem, and some users attempted to run in very_degraded mode got things very borked. For users: - there's a no_splitbrain_check option which runs the splitbrain checks in dry run mode, that should suffice to get most people going - if your fs is very borked, 'scan entire device for btree nodes and reconstruct' is almost done; it looks like that will be a pretty bulletproof way to reconstruct. Some poeple may have their filesystems unavailable for a bit but I'm trying to make sure no one looses data, and no one should be forced to migrate either, we should always get back to a working functional rw fs. Cheers, Kent The following changes since commit be28368b2ccb328b207c9f66c35bb088d91e6a03: bcachefs: time_stats: shrink time_stat_buffer for better alignment (2024-03-13 21:38:03 -0400) are available in the Git repository at: https://evilpiepirate.org/git/bcachefs.git tags/bcachefs-2024-03-19 for you to fetch changes up to 2e92d26b25432ec3399cb517beb0a79a745ec60f: bcachefs: Fix lost wakeup on journal shutdown (2024-03-18 23:35:42 -0400) ---------------------------------------------------------------- bcachefs fixes for 6.9-rc1 Assorted bugfixes. Most are fixes for simple assertion pops; the most significant fix is for a deadlock in recovery when we have to rewrite large numbers of btree nodes to fix errors. This was incorrectly running out of the same workqueue as the core interior btree update path - we now give it its own single threaded workqueue. This was visible to users as "bch2_btree_update_start(): error: BCH_ERR_journal_reclaim_would_deadlock" - and then recovery hanging. ---------------------------------------------------------------- Kent Overstreet (17): bcachefs: Change "accounting overran journal reservation" to a warning bcachefs: Fix check_key_has_snapshot() call bcachefs: Fix spurious -BCH_ERR_transaction_restart_nested bcachefs: Avoid extent entry type assertions in .invalid() bcachefs: Fix locking in bch2_alloc_write_key() bcachefs: Split out btree_node_rewrite_worker bcachefs: Improve sysfs internal/btree_updates bcachefs: Fix nested transaction restart handling in bch2_bucket_gens_init() bcachefs: bch2_snapshot_is_ancestor() now safe to call in early recovery bcachefs: fix for building in userspace bcachefs: Don't corrupt journal keys gap buffer when dropping alloc info bcachefs: Fix lost transaction restart error bcachefs: Improve bch2_fatal_error() bcachefs: Run check_topology() first bcachefs: ratelimit errors from async_btree_node_rewrite bcachefs; Fix deadlock in bch2_btree_update_start() bcachefs: Fix lost wakeup on journal shutdown fs/bcachefs/alloc_background.c | 15 +++++++------ fs/bcachefs/alloc_foreground.c | 10 +++++---- fs/bcachefs/bcachefs.h | 2 ++ fs/bcachefs/btree_gc.c | 2 +- fs/bcachefs/btree_io.c | 12 +++++----- fs/bcachefs/btree_key_cache.c | 2 +- fs/bcachefs/btree_update_interior.c | 44 ++++++++++++++++++++++++------------- fs/bcachefs/btree_update_interior.h | 1 + fs/bcachefs/btree_write_buffer.c | 2 +- fs/bcachefs/buckets.c | 6 ++--- fs/bcachefs/debug.c | 2 +- fs/bcachefs/ec.c | 6 ++--- fs/bcachefs/error.h | 4 ++-- fs/bcachefs/extents.h | 6 ++--- fs/bcachefs/fs.c | 3 ++- fs/bcachefs/fsck.c | 33 ++++++++++++++++++++-------- fs/bcachefs/journal.c | 12 +++++----- fs/bcachefs/journal_io.c | 15 ++++++------- fs/bcachefs/logged_ops.c | 4 ++-- fs/bcachefs/movinggc.c | 3 +-- fs/bcachefs/recovery.c | 6 ++++- fs/bcachefs/recovery_types.h | 2 +- fs/bcachefs/snapshot.c | 32 +++++++++++++++------------ fs/bcachefs/super-io.c | 8 +++---- fs/bcachefs/super.c | 33 ++++++++++++++-------------- fs/bcachefs/util.h | 3 +++ 26 files changed, 157 insertions(+), 111 deletions(-)
