 In 3.19-rc1, all initrd decompressors are by default enabled...

Interesting, this seems to be the opposite of the intention of the
change that caused it, which tried to let you disable the algorithms
without selecting CONFIG_EXPERT. For some reason that is impossible
to know now, they already defaulted to 'n' when EXPERT was set, but
now they default to 'y'.

Does this indeed cause the entire change in size?

 The data, since I started keeping track of it, is below.  The last numeric 
 column represents the total kernel object size delta in bytes.

I see.

So 3.16 was by far the largest increase, almost 10x bigger than the 3.19 
increase, but
others are quite big as well.

Do you know what happened in 3.16?

It was commit 1413c03893332366e5b4d1e26f942ada25f3e82a (lockdep: Increase 
static allocations).

commit 1413c03893332366e5b4d1e26f942ada25f3e82a
Author: Sasha Levin sasha.le...@oracle.com
Date:   Wed Jan 8 14:21:46 2014 -0500

lockdep: Increase static allocations

Fuzzing a recent kernel with a large configuration hits the static
allocation limits and disables lockdep.

This patch doubles the limits.

Actually, no. It seems a bigger contributor is enabling SATA
in omap2plus_defconfig. But there still something else... Below is some
data based on quick checks.
