[PATCH] Make initrd compression algorithm selection not expert

From: Andi Kleen
Date: Thu Oct 09 2014 - 18:29:17 EST


From: Andi Kleen <ak@xxxxxxxxxxxxxxx>

The kernel has support for (nearly) every compression algorithm known to man,
each to handle some particular microscopic niche.

Unfortunately all of these always get compiled in if you want to support INITRDs,
and can be only disabled when CONFIG_EXPERT is set.

I don't see why I need to set EXPERT just to properly configure the
initrd compression algorithms, and not always include every possible algorithm

Usually the initrd is just compressed with gzip anyways, at least that's
true on all distributions I use.

Remove the dependencies for initrd compression on CONFIG_EXPERT.

Make the various options just default y, which should be good
enough to not break any previous configuration.
