I just recently read a post about SSD triming (discard vs fstrim):

"Red Hat recommends batch discard operations ..." (fstrim)
In addition to the RH doc referenced by LF, I found this web page useful:

interesting article. it shows the passthrough of the discard option with dm-crypt involved. rhel seems to not provide such "dm-crypt/trim" support.

"The only DM targets that do not support discards are dm-snapshot, dm-crypt, and dm-raid45."
maybe with the next minor release?
