#     vf/remap: return the amount of bytes actually deduplicated
#     
#     When using the FIDEDUPRANGE ioctl, in case of success the requested size
#     is returned. In some cases this might not be the actual amount of bytes
#     deduplicated.
#     
#     This change modifies vfs_dedupe_file_range() to report the actual amount
#     of bytes deduplicated, instead of the requested amount.
