Can a single scatterlist entry point to memory area consisting of multiple pages?
I am writing a linux kernel device driver and setting a memory region into a 'struct scatterlist' entry. The memory region I am using can span across multiple physical pages. Can the size of memory area being set into scatterlist entry be bigger than a single page size?
