Yes, if you don't build ext4 as a module, then crc32c will be
built-into the kernel as well, and the problem won't occur.  What
worries me is that most people building custom kernels generally will
build in the modules that they need, since it is the optimal thing to
do.  It will be those who build ext4 and crc32c as a module, and use
an ext4 root file system, that will be hit by this.

If we get reports, we should try to get what distro's they are
running, since it's probably going to be distro-dependent.  Hopefully,
I'm worrying over nothing.  :-)
