Subject: [PATCH v6 00/26] add block layout driver to pnfs client
Date: Sat, 30 Jul 2011 13:08:23 -0400 [thread overview]
Message-ID: <1312045729-27554-1-git-send-email-rees@umich.edu> (raw)
This patch set adds a block layout driver to the pNFS client. It passes
Connectathon tests and is bisectable. It requires an updated version of
nfs-utils, and patches for that have been sent separately to the nfs-utils
maintainer.
This patch set is also available on the for-trond branch of the git repo at
git://citi.umich.edu/projects/linux-pnfs-blk.git
This is version 6 of this patch set. Changes since version 5:
- rearrange layoutcommit lwb and cred patches per Boaz
"[PATCHSET 0/6] Patches needed for Stable" 29 Jul 2011 23:19:52 -0700
and put these patches first
- add prefix to exported symbols, or make them static
Changes since version 4:
- rm inode and pnfs_layout_hdr args from cleanup_layoutcommit()
Changes since version 3:
- Rebase to trond/nfs-for-3.1 (commit ed1e6211a0).
- Change return value NFS4ERR_REP_TOO_BIG to EIO in decode_getdevicelist.
- fix error message in set_pnfs_layoutdriver.
- remove dont_like_caller from read_pagelist and write_pagelist.
- rename mark_for_commit to bl_mark_for_commit
- split the patch "NFS41: Let layoutcommit handle multiple segments" into 4
patches each does one task only.
- fix race in saving cred in layout header.
- move the patch "NFS41: save layoutcommit cred after first successful
layoutget" to an earlier place.
- "[PATCH v3 25/25] NFS41: Drop lseg ref before fallthru to MDS" is dropped.
- move GETDEVICELIST to end of nfs4_procedures[]
Changes since version 2:
- Rebase to trond/nfs-for-next (commit ed1e6211a0).
- Fix Fred's and Benny's email addresses.
- Use FIXME to flag code that needs more work.
- Remove obsolete comments.
- Minor patch re-orgs per reviewer comments.
