Hi Linus, fresh batch of fixes for you... Cheers, Kent The following changes since commit bd4da0462ea7bf26b2a5df5528ec20c550f7ec41: bcachefs: Move the ei_flags setting to after initialization (2024-06-21 10:17:07 -0400) are available in the Git repository at: https://evilpiepirate.org/git/bcachefs.git tags/bcachefs-2024-06-28 for you to fetch changes up to 64cd7de998f393e73981e2aa4ee13e4e887f01ea: bcachefs: Fix kmalloc bug in __snapshot_t_mut (2024-06-25 20:51:14 -0400) ---------------------------------------------------------------- bcachefs fixes for 6.10-rc6 simple stuff: - null ptr/err ptr deref fixes - fix for getting wedged on shutdown after journal error - fix missing recalc_capacity() call, capacity now changes correctly after a device goes read only however: our capacity calculation still doesn't take into account when we have mixed ro/rw devices and the ro devices have data on them, that's going to be a more involved fix to separate accounting for "capacity used on ro devices" and "capacity used on rw devices" - boring syzbot stuff slightly more involved: - discard, invalidate workers are now per device this has the effect of simplifying how we take device refs in these paths, and the device ref cleanup fixes a longstanding race between the device removal path and the discard path - fixes for how the debugfs code takes refs on btree_trans objects we have debugfs code that prints in use btree_trans objects. It uses closure_get() on trans->ref, which is mainly for the cycle detector, but the debugfs code was using it on a closure that may have hit 0, which is not allowed; for performance reasons we cannot avoid having not-in-use transactions on the global list. introduce some new primitives to fix this and make the synchronization here a whole lot saner ---------------------------------------------------------------- Kent Overstreet (10): bcachefs: Fix freeing of error pointers bcachefs: fix seqmutex_relock() bcachefs: Make btree_deadlock_to_text() clearer closures: closure_get_not_zero(), closure_return_sync() bcachefs: Fix race between trans_put() and btree_transactions_read() bcachefs: Fix btree_trans list ordering bcachefs: Add missing recalc_capacity() call bcachefs: Fix null ptr deref in journal_pins_to_text() bcachefs: Add missing bch2_journal_do_writes() call bcachefs: Discard, invalidate workers are now per device Pei Li (3): bcachefs: slab-use-after-free Read in bch2_sb_errors_from_cpu bcachefs: Fix shift-out-of-bounds in bch2_blacklist_entries_gc bcachefs: Fix kmalloc bug in __snapshot_t_mut fs/bcachefs/alloc_background.c | 263 +++++++++++++++++++----------------- fs/bcachefs/alloc_background.h | 6 +- fs/bcachefs/alloc_foreground.c | 4 +- fs/bcachefs/bcachefs.h | 16 ++- fs/bcachefs/btree_iter.c | 19 +-- fs/bcachefs/chardev.c | 9 +- fs/bcachefs/debug.c | 109 +++++++++------ fs/bcachefs/journal.c | 5 + fs/bcachefs/journal_io.c | 7 + fs/bcachefs/journal_seq_blacklist.c | 2 +- fs/bcachefs/sb-errors.c | 14 +- fs/bcachefs/seqmutex.h | 11 +- fs/bcachefs/snapshot.c | 3 + fs/bcachefs/super.c | 6 +- include/linux/closure.h | 23 ++++ lib/closure.c | 52 ++++++- 16 files changed, 342 insertions(+), 207 deletions(-)
