[PATCH 07/18] staging/lustre/osc: get rid of old checksum initial value

From: Oleg Drokin
Date: Sun Jun 22 2014 - 21:34:52 EST


From: Bobi Jam <bobijam.xu@xxxxxxxxx>

Old code residue assumes initial checksum value as ~0, and relies on
that to check whether OST server has calculated bulk data checksum.
That is not the case anymore.
