Hi Linus, some more fixes for you, and some compatibility work so that
6.7 will be able to handle the disk space accounting rewrite when it
rolls out.

Happy new year!

The following changes since commit 453f5db0619e2ad64076aab16ff5a00e0f7c53a2:

  bcachefs: make RO snapshots actually RO (2024-01-01 11:47:07 -0500)

----------------------------------------------------------------
More bcachefs bugfixes for 6.7, and forwards compatibility work:

 - fix for a nasty extents + snapshot interaction, reported when reflink
   of a snapshotted file wouldn't complete but turned out to be a more
   general bug
 - fix for an invalid free in dio write path when iov vector was longer
   than our inline vecotr
 - fix for a buffer overflow in the nocow write path - BCH_REPLICAS_MAX
   doesn't actually limit the number of pointers in an extent when
   cached pointers are included
 - RO snapshots are actually RO now
 - And, a new superblock section to avoid future breakage when the disk
   space acounting rewrite rolls out: the new superblock section
   describes versions that need work to downgrade, where the work
   required is a list of recovery passes and errors to silently fix.
