This patch set introduces sg_pcopy_from_buffer() and sg_pcopy_to_buffer(),
which copy data between a linear buffer and an SG list.
The only difference between sg_pcopy_{from,to}_buffer() and
sg_copy_{from,to}_buffer() is an additional argument that specifies
the number of bytes to skip the SG list before copying.
The main reason for introducing these functions is to fix a problem
in scsi_debug module. And there is a local function in crypto/talitos
module, which can be replaced by sg_pcopy_to_buffer().
Akinobu Mita (3):
lib/scatterlist: introduce sg_pcopy_from_buffer() and
sg_pcopy_to_buffer()
crypto: talitos: use sg_pcopy_to_buffer()
scsi_debug: fix do_device_access() with wrap around range
