commit 6c2f32376c59f08a893cd4736d92f000618dd88f
Author: Andre Noll <maan@...temlinux.org>

    Improve raid printout for raid levels 4 and 6.
    
    As noted by Justin Piszcz we currently log a "RAID5 conf printout:" message
    also for raid4 and raid6 arrays. This trivial patch prints the correct raid
    level, adds KERN_INFO to all printk's in print_raid5_conf() and fixes a minor
    coding style issue.
