Subject: [RFC 0/27] pnfs-submit for 2.6.40
Date: Wed, 20 Apr 2011 19:46:25 +0300	[thread overview]
Message-ID: <4DAF0DE1.6020609@panasas.com> (raw)

I prepared an initial version of the pnfs patch series candidate for 2.6.40.
It implements basic support for layout segments and error handling
(fallback to the MDS) for non-rpc based layout drivers.

Comments welcome! :)

The patches are also available in
git://linux-nfs.org/~bhalevy/linux-pnfs.git pnfs-submit

On top of it I rebased the following branches to allow easier testing:
pnfs-submit
    pnfs-obj
        pnfs
            pnfsd-all
                pnfsd-lexp-all
                    pnfs-exofs-all

These branches do not include the pnfs-block implementation yet.

generic pnfs additions:
[RFC 01/27] pnfs: CB_NOTIFY_DEVICEID
[RFC 02/27] pnfs: direct i/o
[RFC 13/27] pnfs: client stats

for pnfs-obj:
[RFC 03/27] pnfs: layoutreturn
[RFC 04/27] pnfs: layoutret_on_setattr
[RFC 05/27] pnfs: Use byte-range layout segments
[RFC 06/27] pnfs: encode_layoutreturn
[RFC 07/27] pnfs: encode_layoutcommit
[RFC 08/27] pnfs: {setup,cleanup}_layoutcommit
[RFC 09/27] pnfs: support for non-rpc layout drivers
[RFC 10/27] pnfs: {,un}set_layoutdriver methods
[RFC 11/27] pnfs: per mount layout driver private data
[RFC 12/27] pnfs: alloc and free layout_hdr layoutdriver methods
[RFC 14/27] pnfsd: introduce exp_xdr.h

pnfs-obj
[RFC 15/27] pnfs-obj: pnfs_osd XDR definitions
[RFC 16/27] pnfs-obj: pnfs_osd XDR client implementations
[RFC 17/27] exofs: pnfs-tree: Remove pnfs-osd private definitions
[RFC 18/27] pnfs-obj: Define PNFS_OBJLAYOUT Kconfig option
[RFC 19/27] pnfs-obj: objlayout driver skeleton
[RFC 20/27] pnfs-obj: objio_osd device information retrieval and caching
[RFC 21/27] pnfs-obj: objio_osd real IO implementation
[RFC 22/27] sunrpc: New xdr_rewind_stream()
[RFC 23/27] pnfs-obj: objlayout_encode_layoutreturn Implementation.
[RFC 24/27] pnfs-obj: objio_osd report osd_errors for layoutreturn
[RFC 25/27] pnfs-obj: objlayout_encode_layoutcommit implementation
[RFC 26/27] pnfs-obj: objio_osd: RAID0 support
[RFC 27/27] pnfs-obj: objio_osd: groups support

* Need to move to xdr_stream based decoding.
* Boaz has some changes queued up, including using a common
  I/O engine for exofs and the pnfs-obj layout driver.
