The 'f' ioctls with numbers 19-26 decimal are currently used for fscrypt
(a.k.a. ext4/f2fs/ubifs encryption), and up to 39 decimal is reserved
for future fscrypt use, as per the comment in fs/ext4/ext4.h. So the
reserved range is 13-27 hex.
Document this in ioctl-number.rst.

Applied to fscrypt.git for 5.5.
