[PATCH v3 0/4] Patches for pNFS SCSI layout PR key registration

[cel@kernel.org]

From: Chuck Lever <chuck.lever@oracle.com>

I've dropped the alloc_bulk_pages_array() patch, as it seemed
slightly less reliable than allocating a page at a time on my
small-memory test system.

I do not currently have a set up that can test slice/concat
configurations, but the simple/scsi volume type is stable (except
for generic/450).

Changes since v2:
- Support more complex volume types
- Dropped the alloc_bulk_pages_array() patch

Changes since RFC:
- series re-ordered to place fixes first
- address review comments as best I can
