Looking at 
http://blog.neutrino.es/2013/howto-properly-activate-trim-for-your-ssd-on-linux-fstrim-lvm-and-dmcrypt/ 
it looks like I needed /etc/lvm/lvm.conf enabling discards.

Then, looking at 
https://unix.stackexchange.com/questions/85865/trim-with-lvm-and-dm-crypt/85880#85880 
it didn't seem to work. I presume because I didn't reboot first. But I 
don't feel like rebooting right now. Grrr.
