Title:
Potential raid0 data corruption when using trim
Status in linux package in Ubuntu:
Incomplete
Bug description:
There's a scary issue with fstrim on raid0 and raid10 mdadm devices.
It is fixed upstream in linux/4.1.5-1, linux/3.16.7-ckt17-1, but I
can't find anything in the changelogs for ubuntu.
Here's the links:

I did my amateur analysis by extracting sources for current trusty
kernel 3.13.0-65-generic and current trusty-lts-utopic
3.16.0-50-generic and looking at files referenced in patches from the
Martin K. Petersen's email, and it appears that 3.16 already has this
fix included, and 3.13 is a completely different code base, so it
isn't clear whether it is affected or not.
I've disabled fstrim in cron until I understand the situation better.
Could someone knowledgeable chime in on the status of this on Ubuntu,
specifically Trusty and after?
