Linus Torvalds 9e87705289 Merge tag 'bcachefs-2023-10-30' of https://evilpiepirate.org/git/bcachefs
Pull initial bcachefs updates from Kent Overstreet:
 "Here's the bcachefs filesystem pull request.

  One new patch since last week: the exportfs constants ended up
  conflicting with other filesystems that are also getting added to the
  global enum, so switched to new constants picked by Amir.

  The only new non fs/bcachefs/ patch is the objtool patch that adds
  bcachefs functions to the list of noreturns. The patch that exports
  osq_lock() has been dropped for now, per Ingo"
