Yes, I noticed that. But I'd rather move it over manually in
another patch post rc1 or for the next merge window.

Well, if we think such a printk is useful it should probably be
moved to the caller in init/initramfs.c instead. I can include a
patch for that in the next iteration of the series.

Maybe. But I'd rather keep it out of the initial series as it looks
a little more complicated. Having a single implementation
of free_initrd_mem would be great, though.
