[GIT PULL] bcachefs fixes for 6.10-rc2

[Kent Overstreet]

Hi Linus, assorted odds and ends...

important note for users: BCH_DATA_unstriped (accounting for unstriped
data in stripe buckets) is arriving next merge window (which requires
regenerating alloc info on mount if erasure coding is enabled), and the
disk accounting rewrite (at long last!) is also in my master branch and
arriving next merge window - which requires regenerating alloc info for
everyone.

disk accounting rewrite brings per-snapshot-id accounting, per-btree
accounting, accounting for pending rebalance work, compression
type/ratio accounting.

everything should be in place to make this a smooth upgrade progress,
except for getting a progress indicator plumbed through so users aren't
left wondering "why is my mount so slow? is it hung?" which we're going
to try to do as well.

The following changes since commit d93ff5fa40b9db5f505d508336bc171f54db862e:

  bcachefs: Fix failure to return error on misaligned dio write (2024-05-29 16:40:30 -0400)

----------------------------------------------------------------
bcachefs fixes for 6.10-rc2

- two downgrade fixes
- a couple snapshot deletion and repair fixes, thanks to noradtux for
  finding these and providing the image to debug them
- a couple assert fixes
- convert to folio helper, from Matthew
- some improved error messages
- bit of code reorganization (just moving things around); doing this
  while things are quiet so I'm not rebasing fixes past reorgs
- don't return -EROFS on inconsistency error in recovery, this confuses
  util-linux and has it retry the mount
- fix failure to return error on misaligned dio write; reported as an
  issue with coreutils shred
