From 410d12e5beb78838fc7c6d47d4c433459dc8b857 Mon Sep 17 00:00:00 2001 From: Karel Zak Date: Mon, 10 Dec 2018 11:45:03 +0100 Subject: fstrim: trim also root FS on --fstab The root fs ("/") is optional in many case in /etc/fstab. This patch forces fstrim to read kernel command line for the root= option to get root FS if the entry is missing in your fstab.
