Subject: Re: [PATCH v14 00/17] iov_iter: Improve page extraction (pin or just list)

Hi Jens,

If you decide not to take my patches in this merge window, would you have any
objection to my patches 1-3 and 10-11 in this series going through Steve
French's cifs tree so that he can take my cifs iteratorisation patches?

Patches 1-3 would add filemap_splice_read() and direct_splice_read(), but not
connect them up to anything and 10-11 would add iov_iter_extract_pages().  I
can then give Steve a patch to make cifs use them as part of my patches for
that.

This would only affect cifs.  See my iov-cifs branch:

	https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git/log/?h=iov-cifs

for an example of how this would look.

David
