Hi,
forwarding this patch we received in the Debian bugtracker.
systemd-cryptsetup recognizes option 'allow-discards' in /etc/crypttab
to enable TRIM passthrough to underlying encrypted device. In Debian
this option was changed to 'discard' to avoid hyphen in option name
(see: #648868 and `man crypttab`).
The attached patch makes “discard” a synonym for “allow-discards” in
/etc/crypttab. Please merge it.

Michael
