Am I correct to assume that this would ONLY affect systems that include a RAID-0 filesystem, and that it would not affect other ext4 systems using SSDs with "discard" in /etc/fstab?
It affects all file systems when used with discard on a raid0 device. It is not a bug specific to ext4[1]. If you do not use raid0 with discard you are fine.
UUgh, dumb question, but... I have not used/configured this "discard", but I do have 6 Raid0 arrays spinning on my Arch server. Does this corruption potentially apply to me? Is this "discard" something that would be enabled by default? I have never heard of it, so that is the only thing to that concerns me. From the kernel thread, the fix is out on 5/22. What do I do to test whether I suffered corruption?
