| |
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).
Thanks, Bill -- -------------------------------------------- William D Waddington Bainbridge Island, WA, USA william.waddington@beezmo.com -------------------------------------------- "Even bugs...are unexpected signposts on the long road of creativity..." - Ken Burtch
