Subject: [GIT PULL] bcachefs fixes for 6.12

test dashboard is looking good, rebasing to rc6 fixed the crazy hangs we
were seeing on rc1...

(and they were crazy; processes were getting stuck on inode lock when
lockdep said nothing was holding it).

this fixes one minor regression from the btree cache fixes in the last
pull request (in the scan_for_btree_nodes repair path) - and the
shutdown path fix is the big one here, in terms of bugs closed.

so I would say things are slowing down here, except now that I've got an
easy way to run syzbot reproducers I'm noticing that we're losing a lot
of coverage because mainly we're mostly bailing out when we see
something corrupt. When self healing is flipped on for more stuff
there's probably going to be another flood of syzbot stuff...

  bcachefs: Fix assertion pop in bch2_ptr_swab() (2024-11-12 03:46:57 -0500)

----------------------------------------------------------------
bcachefs fixes for 6.12

- Assorted tiny syzbot fixes
- Shutdown path fix: "bch2_btree_write_buffer_flush_going_ro()"

  The shutdown path wasn't flushing the btree write buffer, leading to
  shutting down while we still had operations in flight. This fixes a
  whole slew of syzbot bugs, and undoubtedly other strange heisenbugs.
