      bcachefs: Fix promotes · 7b474c77
      Kent Overstreet authored
      The recent work to fix data moves w.r.t. durability broke promotes,
      because the caused us to bail out when the extent minus pointers being
      dropped still has enough pointers to satisfy the current number of
      replicas.
      
      Disable this check when we're adding cached replicas.

      bcachefs: Don't run indirect extent trigger unless inserting/deleting · f88d811a
      Kent Overstreet authored
      This fixes a transaction path overflow reported in the snapshot deletion
      path, when moving extents to the correct snapshot.
      
      The root of the issue is that creating/deleting a reflink pointer can
      generate an unbounded number of updates, if it is allowed to reference
      an unbounded number of indirect extents; to prevent this, merging of
      reflink pointers has been disabled.
      
      But there's a hole, which is that copygc/rebalance may fragment existing
      extents in the course of moving them around, and if an indirect extent
      becomes too fragmented we'll then become unable to delete the reflink
      pointer.
      
      The eventual solution is going to be to tweak trigger handling so that
      we can process large reflink pointers incrementally when necessary, and
      notice that trigger updates don't need to be run for the part of the
      reflink pointer not changing. That is going to be a bigger project
      though, for another patch.

      bcachefs: Fix a journal deadlock in replay · 87b0d8d3
      Kent Overstreet authored
      Recently, journal pre-reservations were removed. They were for reserving
      space ahead of time in the journal for operations that are required for
      journal reclaim, e.g. btree key cache flushing and interior node btree
      updates.
      
      Instead we have watermarks - only operations for journal reclaim are
      allowed when the journal is low on space, and in general we're quite
      good about doing operations in the order that will free up space in the
      journal quickest when we're low on space. If we're doing a journal
      reclaim operation out of order, we usually do it in nonblocking mode if
      it's not freeing up space at the end of the journal.
      
      There's an exceptino though - interior btree node update operations have
      to be BCH_WATERMARK_reclaim - once they've been started, and they can't
      be nonblocking. Generally this is fine because they'll only be a very
      small fraction of transaction commits - but there's an exception, which
      is during journal replay.
      
      Journal replay does many btree operations, but doesn't need to commit
      them to the journal since they're already in the journal. So killing off
      of pre-reservation, plus another change to make journal replay more
      efficient by initially doing the replay in sorted btree order, made it
      possible for the interior update operations replay generates to fill and
      deadlock the journal.
      
      Fix this by introducing a new check on journal space at the _start_ of
      an interior update operation. This causes us to block if necessary in
      exactly the same way as we used to when interior updates took a journal
      pre-reservaiton, but without all the expensive accounting
      pre-reservations required.

      bcachefs; Don't use btree write buffer until journal replay is finished · ef6fae4a
      Kent Overstreet authored
      The keys being replayed by journal replay have to be synchronized with
      updates by other threads that overwrite them. We rely on btree node
      locks for synchronizing - but since btree write buffer updates take no
      btree locks, that won't work.
      
      Instead, simply disable using the btree write buffer until journal
      replay is finished.
      
      This fixes a rare backpointers error in the merge_torture_flakey test.

      Pull io_uring fixes from Jens Axboe:
      
       - Fix an issue with discontig page checking for IORING_SETUP_NO_MMAP
      
       - Fix an issue with not allowing IORING_SETUP_NO_MMAP also disallowing
         mmap'ed buffer rings
      
       - Fix an issue with deferred release of memory mapped pages
      
       - Fix a lockdep issue with IORING_SETUP_NO_MMAP
      
       - Use fget/fput consistently, even from our sync system calls. No real
         issue here, but if we were ever to allow closing io_uring descriptors
         it would be required. Let's play it safe and just use the full ref
         counted versions upfront. Most uses of io_uring are threaded anyway,
         and hence already doing the full version underneath.

      Pull device mapper fixes from Mike Snitzer:
      
       - Fix DM verity target's FEC support to always initialize IO before it
