Would it make sense to give the draft more time to stabilize before merging in code to prevent compatibility issues? They are not that big and this current set of XDR has been in there for over 2 months. Bringing the current code up to draft version 4 would take a day. And I’d have to spend the same amount of time on the server code to do testing. The changes from version 4 to version 5 will be localized to the ff_layoutupdate4 structure (note that draft 4 has this as layoutupdate4). > > Anna > > > > > Enjoy, > > Tom > > > > Peng Tao (36): > > nfs41: pull data server cache from file layout to generic pnfs > > nfs41: pull nfs4_ds_connect from file layout to generic pnfs > > nfs41: pull decode_ds_addr from file layout to generic pnfs > > nfs41: allow LD to choose DS connection auth flavor > > nfs41: move file layout macros to generic pnfs > > nfsv3: introduce nfs3_set_ds_client > > nfs41: allow LD to choose DS connection version/minor_version > > nfs41: create NFSv3 DS connection if specified > > nfs: allow different protocol in nfs_initiate_commit > > nfs4: pass slot table to nfs40_setup_sequence > > nfs4: export nfs4_sequence_done > > nfs: allow to specify cred in nfs_initiate_pgio > > nfs: set hostname when creating nfsv3 ds connection > > nfs/flexclient: export pnfs_layoutcommit_inode > > nfs41: close a small race window when adding new layout to global list > > nfs41: serialize first layoutget of a file > > nfs: save server READ/WRITE/COMMIT status > > nfs41: pass iomode through layoutreturn args > > nfs41: make a helper function to send layoutreturn > > nfs41: add a helper to mark layout for return > > nfs41: don't use a layout if it is marked for returning > > nfs41: send layoutreturn in last put_lseg > > nfs41: clear NFS_LAYOUT_RETURN if layoutreturn is sent or failed to > > send > > nfs/filelayout: use pnfs_error_mark_layout_for_return > > nfs41: add a debug warning if we destroy an unempty layout > > nfs/flexfiles: send layoutreturn before freeing lseg > > nfs: only reset desc->pg_mirror_idx when mirroring is supported > > nfs: add nfs_pgio_current_mirror helper > > pnfs: allow LD to ask to resend read through pnfs > > nfs41: add range to layoutreturn args > > nfs41: allow async version layoutreturn > > nfs41: introduce NFS_LAYOUT_RETURN_BEFORE_CLOSE > > nfs/flexfiles: defer sending layoutreturn in pnfs_put_lseg > > nfs41: add NFS_LAYOUT_RETRY_LAYOUTGET to layout header flags > > nfs: add a helper to set NFS_ODIRECT_RESCHED_WRITES to direct writes > > nfs41: wait for LAYOUTRETURN before retrying LAYOUTGET > > > > Tom Haynes (4): > > pnfs: Prepare for flexfiles by pulling out common code > > pnfs: Do not grab the commit_info lock twice when rescheduling writes > > pnfs: Add nfs_rpc_ops in calls to nfs_initiate_pgio > > pnfs/flexfiles: Add the FlexFile Layout Driver > > > > Trond Myklebust (1): > > NFSv4.1/NFSv3: Add pNFS callbacks for nfs3_(read|write|commit)_done() > > > > Weston Andros Adamson (9): > > sunrpc: add rpc_count_iostats_idx > > nfs: introduce pg_cleanup op for pgio descriptors > > pnfs: release lseg in pnfs_generic_pg_cleanup > > nfs: handle overlapping reqs in lock_and_join > > nfs: rename pgio header ds_idx to ds_commit_idx > > pnfs: pass ds_commit_idx through the commit path > > nfs: add mirroring support to pgio layer > > nfs: mirroring support for direct io > > pnfs: fail comparison when bucket verifier not set > > > > fs/nfs/Kconfig | 5 + > > fs/nfs/Makefile | 3 +- > > fs/nfs/blocklayout/blocklayout.c | 2 + > > fs/nfs/direct.c | 108 +- > > fs/nfs/filelayout/filelayout.c | 315 +----- > > fs/nfs/filelayout/filelayout.h | 40 - > > fs/nfs/filelayout/filelayoutdev.c | 469 +-------- > > fs/nfs/flexfilelayout/Makefile | 5 + > > fs/nfs/flexfilelayout/flexfilelayout.c | 1575 +++++++++++++++++++++++++++++ > > fs/nfs/flexfilelayout/flexfilelayout.h | 152 +++ > > fs/nfs/flexfilelayout/flexfilelayoutdev.c | 519 ++++++++++ > > fs/nfs/internal.h | 34 +- > > fs/nfs/nfs3client.c | 41 + > > fs/nfs/nfs3proc.c | 9 + > > fs/nfs/nfs3super.c | 2 +- > > fs/nfs/nfs3xdr.c | 3 + > > fs/nfs/nfs4_fs.h | 6 + > > fs/nfs/nfs4client.c | 7 +- > > fs/nfs/nfs4proc.c | 45 +- > > fs/nfs/nfs4xdr.c | 9 +- > > fs/nfs/objlayout/objio_osd.c | 5 +- > > fs/nfs/pagelist.c | 294 +++++- > > fs/nfs/pnfs.c | 407 ++++++-- > > fs/nfs/pnfs.h | 119 ++- > > fs/nfs/pnfs_dev.c | 522 ++++++++++ > > fs/nfs/pnfs_nfsio.c | 283 ++++++ > > fs/nfs/read.c | 33 +- > > fs/nfs/write.c | 49 +- > > include/linux/nfs4.h | 1 + > > include/linux/nfs_page.h | 22 +- > > include/linux/nfs_xdr.h | 6 +- > > include/linux/sunrpc/metrics.h | 2 + > > net/sunrpc/stats.c | 26 +- > > 33 files changed, 4119 insertions(+), 999 deletions(-) > > create mode 100644 fs/nfs/flexfilelayout/Makefile > > create mode 100644 fs/nfs/flexfilelayout/flexfilelayout.c > > create mode 100644 fs/nfs/flexfilelayout/flexfilelayout.h > > create mode 100644 fs/nfs/flexfilelayout/flexfilelayoutdev.c > > create mode 100644 fs/nfs/pnfs_nfsio.c > > > -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
