Public bug reported:

Dear all,

In order to be able to upgrade one of our servers to the latest LTS (14.04), we need that the Samsung SSD 8 series to be blacklisted from the libata for the TRIM command.
Due to the bug described here [1],  not having the SSD blacklisted would lead to data corruption which we cannot afford.
The Samsung SSD was blacklisted with that commit [2].

I checked, it's not present in current Trusty kernel. Could you please
backport it?

With my best regards,
