Hello Jens, As you know there are multiple drivers that both allocate a scatter/gather list and populate that list with pages. This patch series moves the code for allocating and freeing such scatterlists from several drivers into lib/scatterlist.c. Please consider this patch series for kernel v4.16.
Changes between v3 and v4: - Left out patches 6..8 as requested by Martin Petersen. These patches will be sent to Martin after this series has been merged. Changes between v2 and v3: - Added Reviewed-by tags that had been posted as replies on v2. - Cc'ed the crypto maintainers for the entire patch series. Changes between v1 and v2: - Moved the sgl_alloc*() and sgl_free() functions from a new source file into lib/scatterlist.c. - Changed the argument order for the sgl_alloc*() functions such that the (pointer to) the output argument comes last.
