[PATCH v4 0/5] Introduce sgl_alloc() and sgl_free()

[Bart Van Assche]

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.

Bart Van Assche (5):
  lib/scatterlist: Introduce sgl_alloc() and sgl_free()
  crypto: scompress - use sgl_alloc() and sgl_free()
  nvmet/fc: Use sgl_alloc() and sgl_free()
  nvmet/rdma: Use sgl_alloc() and sgl_free()
  target: Use sgl_alloc_order() and sgl_free()
