From d7b16e4f6283c6ec52b411aa6deb02ca4d030d20 Mon Sep 17 00:00:00 2001 From: "Martin K. Petersen" Date: Mon, 4 May 2015 21:54:18 -0400 Subject: libata: Allow NCQ TRIM to be enabled or disabled with a module parameter We have started seeing SSD firmware updates introduce support for queued TRIM. Sadly, in most cases this support is completely untested and can lead to either errors or data corruption. Add two libata force flags that can be used to either enable or disable queued TRIM support.
