I don't find any place that S390 changes CONFIG_BLK_DEV_RAM_SIZE from its default
of 4096 to 8192. Did you? If so, where please?

Compare to ramdisk_size? how about
See ramdisk_size.
or
Same as ramdisk_size.

As for the Changelog, it would be better just to delete all of it.
That's what git is for (and good at).

You're right, it's an old S390 recommendation.I'm removing it as well :)

Git only gives post 2008 updates.I guess we keep previous changelogs in text mode where
available ?
I had no reaction to this patch (also about ramdisk)
https://lkml.org/lkml/2013/12/6/748
Should I merge it to this one ?
