Ignore the above.

As it turns out crc32c-generic is built into the kernel, crc32c-intel
is built as a module. Btrfs initially is using generic, but switches
to intel once it's available.

cat /sys/fs/btrfs/$FSUUID/checksum/
crc32c (crc32c-intel)

Where $FSUUID is the UUID for the Btrfs file system you're inquiring
about; lsblk -f or blkid.
