Christoph asked if I c= ould pare down the patchset to the minimum to fix the bio case for the moment. It will be easier to do the others once iov_iter_extract_pages() is upstre= am as the individual bits can go via their respective maintainers. However, I do want to see about adding cifs iteratorisation in this merge window also, which also depends on the iov_iter_extract_pages() function b= eing added. David
