Re: [PATCH 1/3] lib/scatterlist: introduce sg_pcopy_from_buffer() and sg_pcopy_to_buffer()

2013/6/6 Imre Deak [off-list ref]:

Looks ok to me, perhaps adding the seek functionality to the mapping
iterator would make things more generic and the mapping iterator more
resemble the page iterator. So we'd have a new sg_miter_start_offset and
call it here something like:

sg_miter_start_offset(&miter, sgl, nents, sg_flags, skip);

I also thought something like this could be a new interface for sg_miter_* API,
but I haven't found any places where it can be used yet.  That's why I made
it a local function and didn't create new interface.

But putting good function comment like other sg_miter_* API for new
local function
is harmless and it helps someone who wants interface like this in the future.
So I'll do so in next version.
