I think that use of request_module("crct10dif") does not help loading
crct10dif-pclmul.ko when CONFIG_CRC_T10DIF=y CONFIG_CRYPTO_CRCT10DIF_PCLMUL=m ,
for there is no / directory (note that the initramfs is not yet mounted as /
for loading modules which are not in vmlinux) when any module_init() functions
which are in vmlinux are called.
