These are the accumulated osd patches for the next merge window,
Linux 2.6.31.

Most of these patches are a repost rebased on latest scsi-misc

List of patches:
[PATCH 01/10 resend] libosd: OSD2r05: Additional command enums
[PATCH 02/10 resend] libosd: OSD2r05: Attribute definitions
[PATCH 03/10 resend] libosd: Better printout of OSD target system information
[PATCH 04/10 resend] libosd: osd_req_{read,write}_kern new API
[PATCH 05/10 resend] libosd: Let _osd_req_finalize_data_integrity receive number of out_bytes
[PATCH 06/10 resend] libosd: osd_req_{read,write} takes a length parameter

These are a resend. The last 2 patches are important for supporting Jeff's
osdblk driver. (The first 4 are old patches that thier time has come)

[PATCH 07/10] libosd: Define an osd_dev wrapper to retrieve the request_queue
Simple wrapper

[PATCH 08/10] osduld: use filp_open() when looking up an osd-device

This patch was inspired by Al Viro. It uses the in-kernel open-file
mechanism to look up the osd char-device for Kernel users like exofs
and later pNFS-Objlayout.
It was heavily tested and works well.
It fixes the problem we had before, of need to open+close a file handle
on the osd-char-device before mounting an exofs.
Please review

[PATCH 09/10] libosd: Use REQ_QUIET requests.
Recent scsi_lib changes, caused a dmesg span in exofs+osd regular use,
because of the way we routinely receive a recovered scsi sense. Recently, for
reason I could not find, this condition started to print messages at:
scsi_io_comlition:778 (look for "== RECOVERED_ERROR")
Use of a REQ_QUIET flag is needed to silence these prints.
OSD has it's own prints for scsi-sense returns, when needed.

[PATCH 10/10] osd: Remove out-of-tree left overs
