TL;DR: The btrfs module has dropped it's libcrc32c dependency, so mkinitcpio no longer pulls in the crc32c module necessary for the btrfs module to be inserted. The crc32c module was only pulled in previously due to mkinitcpio hackery [2], so extra hackery now seems like the logical path.

Besides from this extra hackery, an alternative workaround would be for users in this situation to add crc32c to their MODULES aray in their mkintcpio.conf. Of course, this needs to be done ahead of the linux-3.14 upgrade for them to avoid the problem (assuming none of their other modules depend on libcrc32c).

wouldn't it be easier to just add this to the above case?
