From 2ed4392b0bb3e80bdf9d0bfeffc2651910951ff1 Mon Sep 17 00:00:00 2001 From: Juha-Matti Tilli Date: Sun, 2 Dec 2018 12:47:08 +0200 Subject: [PATCH] libata: whitelist all SAMSUNG MZ7KM* solid-state disks [ Upstream commit fd6f32f78645db32b6b95a42e45da2ddd6de0e67 ] These devices support read zero after trim (RZAT), as they advertise to the OS. However, the OS doesn't believe the SSDs unless they are explicitly whitelisted. Acked-by: Martin K.
