Merge tag 'bcachefs-2025-07-03' of git://evilpiepirate.org/bcachefs

Pull bcachefs fixes from Kent Overstreet:
 "The 'opts.casefold_disabled' patch is non critical, but would be a
  6.15 backport; it's to address the casefolding + overlayfs
  incompatibility that was discovvered late.

  It's late because I was hoping that this would be addressed on the
  overlayfs side (and will be in 6.17), but user reports keep coming in
  on this one (lots of people are using docker these days)"
