From 84e86788705c176cc195e4a9831c0be08dcece31 Mon Sep 17 00:00:00 2001 From: Wanpeng Qian Date: Thu, 6 Oct 2022 10:10:06 +0000 Subject: [PATCH] nvmecontrol: Add Samsung Extended SMART Information logpage support Samsung PM983 SSD has a 0xca logpage. It has more information compared to Intel's this patch tested on PM983 M2 SSD and works as expected.
