If you are using SATA SSDs, absolutely.

This bug has been around for a long time and I'm surprised we haven't
heard of it until now. But it's very specific to the way linear, raid0
and raid10 interface with the block layer. I'm guessing that most SSD
users deploy raid1 which is not affected.

The problem is also there if you have a storage array that prefers the
UNMAP command. But it's even less likely that you'd be using software
RAID in that case.
