How to specify custom mount options for root filesystem

SUSE Linux Enterprise Desktop 12
While SUSE is in the process of developing a final fix for this, a workaround would be to:
Edit the grub2 boot loader config at /etc/default/grub and add the:
rootflags=option with the file system flag added to the GRUB_CMDLINE_LINUX_DEFAULT="" variable, for example:
GRUB_CMDLINE_LINUX_DEFAULT="rootflags=discard"Make sure to run:
grub2-mkconfig -o /boot/grub2/grub2.cfgafterwards to enable these settings.
If this variable is not specified, the root filesystem is mounted firstly with the default mount options and then remounted with the options specified in /etc/fstab.
However, some filesystems (e.g. XFS) do not support changing the mount options during remount.
Thus the settings in /etc/fstab are ignored.
