The noswap mount option is surely not one of the three options for sizing:
move its description down.

The huge= mount option does not accept numeric values: those are just in
an internal enum.  Delete those numbers, and follow the manpage text more
closely (but there's not yet any fadvise() or fcntl() which applies here).

/sys/kernel/mm/transparent_hugepage/shmem_enabled is hard to describe, and
barely relevant to mounting a tmpfs: just refer to transhuge.rst (while
still using the words deny and force, to help as informal reminders).
