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 7 of this patch set. Changes since version 6: - sign off on all patches - squash more of "rm inode and pnfs_layout_hdr args from cleanup_layoutcommit()" 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.
