Note that the current iov_iter_get_pages2() is broken, which is why Al wanted a replacement. It should not be taking a ref on the pages in an XARRAY, BVEC or PIPE - and it should be pinning rather than getting a ref on pages in IOVEC or UBUF if the buffer is being read into. I'm guessing that your changes move the latter decision to the caller? David
