Public bug reported:
/usr/lib/zfs-linux/trim, which is run on the first Sunday of every month
via an entry in /etc/cron.d/zfsutils-linux, outputs the following
message if a pool has no devices that support TRIM:
cannot trim: no devices in pool support trim operations
When this occurs via the crontab entry, the result is that cron sends an
E-Mail to root with the output. So systems which have ZFS configured on
a device that does not support TRIM (which includes not just legacy
HDD's, but also dm-crypt devices (by default) even if they have an SSD
lower layer) will get a nuisance E-Mail every month.

[ . . . ]
: What I expected to happen
The cronjob to silently complete without sending an error message (in the case
where the only issue is that the pool has no devices that support TRTM)
: What happened instead
The crontab caused an E-Mail with the above mentioned error message to be send
to root
(Note that there appears to be logic in the script to cause it to
continue past such pools. But that doesn't prevent the message from
being output and E-Mailed.)
