Subject: mkdumprd: make dracut_args an array again


upstream: fedora
resolves: bz2003832
conflict: none

commit 227fc2bc7dcd9ebc328634dc421373624ba22cc2
Author: Kairui Song <kasong@redhat.com>
Date:   Wed Aug 4 03:50:04 2021 +0800

    mkdumprd: make dracut_args an array again

    To make arguments list work as expected, array is preferred.

    Use xargs only to parse the "dracut_args" config value, and pass the
    array directly to dracut.

    Check following link for details:
