crypto: crct10dif - Wrap crc_t10dif function all to use crypto
transform framework
When CRC T10 DIF is calculated using the crypto transform framework, we
wrap the crc_t10dif function call to utilize it. This allows us to
take advantage of any accelerated CRC T10 DIF transform that is
plugged into the crypto framework.

Arthur,
Thanks for reporting the problem.
Can you provide info on to help me trace the issue:
1) What kind of cpu you're using? (can you send info in /proc/cpu)
2) Does your root disk use crct10dif integrity check?
Thanks.
Tim
Hi thanks for your reply.
I've reproduced the problem on x86_64 (AMD Athlon64) and i386 (Pentium 4).
I'm not sure what the root disk is doing, just using Debian's mk-kpkg
kernel_package to build a kernel with an initial ramdisk.
On one of the failed boot-up attempts I saw an error like:
sd_mod - unknown symbol crc*
(where crc* could have been a longer symbol name starting with crt10dif)
I'm happy to look further if I could be given directions on how to find
out if the root disk is using crc10dif integrity check or not.
Regards,
Arthur.
