No, not now. I want to use fstrim in favour to the discard option. But
I've tested it with an Arch Linux installation with a more fresh kernel.
There both vairante (fstrim and discard-option in fstab) fails too. In
case of the discard option, the error is written to the logs.

$ findmnt | grep /media/jd/TEST
├─/media/jd/TEST /dev/sdg1 ext4
rw,nosuid,nodev,relatime,data=ordered
$ sudo lsblk -D
[sudo] password for jd:
NAME DISC-ALN DISC-GRAN DISC-MAX DISC-ZERO
sda 0 512B 2G 0
├─sda1 0 512B 2G 0
└─sda2 0 512B 2G 0
sdb 0 0B 0B 0
sdg 0 0B 0B 0
└─sdg1 0 0B 0B 0
In this case, sda is a internal SSD (Samsung EVO) with working TRIM and
sdb is a HDD.
