Hi, Changes since v9: - Inverted series so that NFSD changes come before NFS. - Addressed many of Chuck's various review comments for "[PATCH v9 13/19] nfsd: add "localio" support" TODO: - Hopefully get a favorable response to this patch from XFS engineers: https://marc.info/?l=linux-xfs&m=171976530416523&w=2 (otherwise, will need to revisit using dedicated workqueue patch) All review and comments are welcome! Thanks, Mike My git tree is here: https://git.kernel.org/pub/scm/linux/kernel/git/snitzer/linux.git/ This v10 is both branch nfs-localio-for-6.11 (always tracks latest) and nfs-localio-for-6.11.v10 Mike Snitzer (10): nfs: factor out {encode,decode}_opaque_fixed to nfs_xdr.h nfs_common: add NFS LOCALIO auxiliary protocol enablement nfsd: add Kconfig options to allow localio to be enabled nfsd: manage netns reference in nfsd_open_local_fh nfsd: use percpu_ref to interlock nfsd_destroy_serv and nfsd_open_local_fh nfsd: implement server support for NFS_LOCALIO_PROGRAM nfs: fix nfs_localio_vfs_getattr() to properly support v4 SUNRPC: remove call_allocate() BUG_ON if p_arglen=0 to allow RPC with void arg nfs: implement client support for NFS_LOCALIO_PROGRAM nfs: add Documentation/filesystems/nfs/localio.rst NeilBrown (1): SUNRPC: replace program list with program array Trond Myklebust (2): nfs: enable localio for non-pNFS I/O pnfs/flexfiles: enable localio for flexfiles I/O Weston Andros Adamson (6): SUNRPC: add rpcauth_map_to_svc_cred_local nfsd: add "localio" support nfs: pass nfs_client to nfs_initiate_pgio nfs: pass descriptor thru nfs_initiate_pgio path nfs: pass struct file to nfs_init_pgio and nfs_init_commit nfs: add "localio" support Documentation/filesystems/nfs/localio.rst | 135 ++++ fs/Kconfig | 3 + fs/nfs/Kconfig | 14 + fs/nfs/Makefile | 1 + fs/nfs/blocklayout/blocklayout.c | 6 +- fs/nfs/client.c | 15 +- fs/nfs/filelayout/filelayout.c | 16 +- fs/nfs/flexfilelayout/flexfilelayout.c | 131 +++- fs/nfs/flexfilelayout/flexfilelayout.h | 2 + fs/nfs/flexfilelayout/flexfilelayoutdev.c | 6 + fs/nfs/inode.c | 4 + fs/nfs/internal.h | 60 +- fs/nfs/localio.c | 827 ++++++++++++++++++++++ fs/nfs/nfs4xdr.c | 13 - fs/nfs/nfstrace.h | 61 ++ fs/nfs/pagelist.c | 32 +- fs/nfs/pnfs.c | 24 +- fs/nfs/pnfs.h | 6 +- fs/nfs/pnfs_nfs.c | 2 +- fs/nfs/write.c | 13 +- fs/nfs_common/Makefile | 3 + fs/nfs_common/nfslocalio.c | 74 ++ fs/nfsd/Kconfig | 14 + fs/nfsd/Makefile | 1 + fs/nfsd/filecache.c | 2 +- fs/nfsd/localio.c | 329 +++++++++ fs/nfsd/netns.h | 12 +- fs/nfsd/nfsctl.c | 2 +- fs/nfsd/nfsd.h | 2 +- fs/nfsd/nfssvc.c | 116 ++- fs/nfsd/trace.h | 3 +- fs/nfsd/vfs.h | 9 + include/linux/nfs.h | 9 + include/linux/nfs_fs.h | 2 + include/linux/nfs_fs_sb.h | 10 + include/linux/nfs_xdr.h | 20 +- include/linux/nfslocalio.h | 42 ++ include/linux/sunrpc/auth.h | 4 + include/linux/sunrpc/svc.h | 7 +- net/sunrpc/auth.c | 15 + net/sunrpc/clnt.c | 1 - net/sunrpc/svc.c | 68 +- net/sunrpc/svc_xprt.c | 2 +- net/sunrpc/svcauth_unix.c | 3 +- 44 files changed, 1986 insertions(+), 135 deletions(-) create mode 100644 Documentation/filesystems/nfs/localio.rst create mode 100644 fs/nfs/localio.c create mode 100644 fs/nfs_common/nfslocalio.c create mode 100644 fs/nfsd/localio.c create mode 100644 include/linux/nfslocalio.h -- 2.44.0
