Ah, I only tried with a non-system partition with "cryptsetup
luksOpen", where it is indeed --allow-discards. (I don't use crypttab
myself). I found "allow-discards" in
http://blog.christophersmart.com/2013/06/05/trim-on-lvm-on-luks-on-ssd/
but I guess I'd rather trust the manpage. Easy enough for someone to
try out who actually uses crypttab :-)

Thanks for pointing out!
