From: Alexander Nezhinsky <alexandern@xxxxxxxxxxxx>
These patches fix data-in buffer generation for SPC and SPC-like commands,
correctly accounting for allocation length, introduce explicit transfer length
reporting by SCSI layer, fix and unify residual count caclulation for
over/underflow conditions by iscsi and iser LLDs.
For an extensive comment please see patch:
"transfer_len for scsi_cmd, set together with resid..."
Alexander Nezhinsky (13):
transfer_len for scsi_cmd, set together with resid; unified resid
handling for iscsi/iser
mem_copy_n32: safe memcpy, accumulates copied count, tracks remaining
space

direction
