cifs_iovec_read: keep iov_iter between the calls of cifs_readdata_to_iov() ... we are doing them on adjacent parts of file, so what happens is that each subsequent call works to rebuild the iov_iter to exact state it had been abandoned in by previous one. Just keep it through the entire cifs_iovec_read(). And use copy_page_to_iter() instead of doing kmap/copy_to_user/kunmap manually... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
