[PATCH v2 0/6] more pgio cleanup

[Weston Andros Adamson <dros@primarydata.com>]

This patchset is more cleanup related to the recent pgio changes.

These patches are on top of trond's testing branch and can be found in my
"pgio_plus" branch at:

git://git.linux-nfs.org/projects/dros/linux-nfs

Most of these patches are dealing with the merge of nfs_pgio_data into
nfs_pgio_header. My recent patchset "[PATCH v3 00/18] nfs: support
multiple requests per page" changes the pgio layer so that an
nfs_pgio_header only ever has one nfs_pgio_data, which allows us to
simplify a lot of things.

Updates in v2:
  - dropped "pnfs: merge identical functions" as Anna Schumaker is working on
    similar cleanups
  - dropped "nfs: clean up function decls in nfs_page.h" as it changed decls
    from the preferred style (thanks Jim Rees).
  - fix "pnfs: clean up *_resend_to_mds" - return nfs_pageio_resend in
     pnfs_read_done_resend_to_mds (thanks Anna Schumaker)

I haven't had time to rename struct nfs_page (as Christoph Hellwig
requested), but I plan on getting to it soon. Now that I mention it,
what should I rename it to?

Trond doesn't like the idea of renaming to nfs_request (or nfs_req) - that's
what they are called everywhere, but it can be confused with other request
structures. These structures describe a region of a page, so maybe something
like 'struct nfs_region'? Not sure I like that name...

I'll be testing all these pgio changes at the bakeathon. I was hoping to at
least get this patchset into the bakeathon branch so others can run it too.


Thanks,
