This is a follow up to the recent change that makes btrfs use the generic
helper for cloning and deduplication [1]. It contains a mix of cleanups
and fixes, which existed before that change.

[1] Btrfs: use generic_remap_file_range_prep() for cloning and deduplication

Filipe Manana (4):
  Btrfs: move duplicated nodatasum check into common reflink/dedupe
    helper
  Btrfs: use cross mount point check for cloning and deduplication
  Btrfs: check if destination root is read-only for deduplication
  Btrfs: remove no longer needed range length checks for deduplication
