CONFIG_BLK_DEV_RAM_SIZE is currently set to 8K, which is a bit on the
smaller side, lets bump it up to 64K so that a bigger RAM_DISK can
be used with defconfig.

Every time I build exynos_defconfig, I need to manually change RAM_SIZE
to match my ramdisk image size. I am not sure what is the best ramdisk size
might be, but bumping it to 64K might be a reasonable one.

I agree that 8KiB is too small and that should be bumped, I'm also
not sure what the best size would be but 64KiB sounds reasonable
to me. So for this patch:

In case you are interested, I got some stats by doing grep on the ARM
defconfigs using this [0]. Of course the sizes depends on the platform
but just to have an idea about what sizes are more popular than others.
SIZE COUNT
1024 17
8192 43
10240 1
16384 20
20000 25

It's _not_ 8KiB or 64KiB.
config BLK_DEV_RAM_SIZE
int "Default RAM disk size (kbytes)"
It's 8MiB or 64MiB - the value you place here is in units of 1024 bytes.

Is there still a reason to use ramdisks these days? If 8MB is not
enough to have a useful initrd, that might mean that everyone else
uses initramfs and you should just do the same thing?
Then we can also remove this option here.

There is not specific reason to still use ramdisks, but I feel till we
remove this config, lets modify it to be used by few like me.
I am ok with either way.
