Message-ID: <482C6A02.2030600@beezmo.com> Date: Thu, 15 May 2008 09:51:14 -0700 From: William D Waddington <william.waddington@...zmo.com> To: linux-kernel@...r.kernel.org Subject: [RFCLUE4] scatterlist changes Hi, I have just tripped over the scatterlist changes in my out-of-tree drivers. I'll deal with it. When the API stabilizes... It does bring to mind a simple question: why limit the scatterlist to a single page, or require a multiple-page list to be dealt with as individual pages? Is this just to avoid vmalloc use? I don't see anything that requires a scatterlist to be in physically contiguous memory (at a quick glance anyway) other than perhaps a preference for the initial allocation mechanism. (My actual IOPB list for the DMA hardware is a different matter entirely, but I don't _think_ I'm confusing the two).
