Subject: Add dm_mod loader
X-Git-Tag: 003~81
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=41f8a4f14f96696b29debde70d9b510c59d5e509;p=thirdparty%2Fdracut.git

Add dm_mod loader

Some kernel configurations might build base dm support as a module.
Add module dm which ensures that dm_mod is there and loaded.
