These latest changes are available in my git tree here: https://git.kernel.org/pub/scm/linux/kernel/git/snitzer/linux.git/log/?h=nfs-localio-for-next Changes since v12: - Rebased to rearrange code to avoid "churn" that Jeff Layton felt distracting (biggest improvement came from folding switch from struct file to nfsd_file changes in from the start of the series) - Updated relevant patch headers accordingly. - Updated localio.rst to provide more performance data. - Dropped v12's buggy "nfsd: fix nfsfh tracepoints to properly handle NULL rqstp" patch -- fixing localio to support fh_verify tracepoints will need more think-time and discussion, but they aren't of critical importance so fixing them doesn't need to hold things up. Please also see v12's patch header for v12's extensive changes: https://marc.info/?l=linux-nfs&m=172409139907981&w=2 Thanks, Mike Mike Snitzer (9): nfs_common: factor out nfs_errtbl and nfs_stat_to_errno nfs_common: factor out nfs4_errtbl and nfs4_stat_to_errno nfs: factor out {encode,decode}_opaque_fixed to nfs_xdr.h SUNRPC: remove call_allocate() BUG_ONs nfs_common: add NFS LOCALIO auxiliary protocol enablement nfsd: implement server support for NFS_LOCALIO_PROGRAM nfs: pass struct nfsd_file to nfs_init_pgio and nfs_init_commit nfs: implement client support for NFS_LOCALIO_PROGRAM nfs: add Documentation/filesystems/nfs/localio.rst NeilBrown (3): nfsd: factor out __fh_verify to allow NULL rqstp to be passed nfsd: add nfsd_file_acquire_local() SUNRPC: replace program list with program array Trond Myklebust (4): nfs: enable localio for non-pNFS IO pnfs/flexfiles: enable localio support nfs/localio: use dedicated workqueues for filesystem read and write nfs: add FAQ section to Documentation/filesystems/nfs/localio.rst Weston Andros Adamson (3): SUNRPC: add rpcauth_map_clnt_to_svc_cred_local nfsd: add localio support nfs: add localio support Documentation/filesystems/nfs/localio.rst | 276 ++++++++ fs/Kconfig | 3 + fs/nfs/Kconfig | 15 + fs/nfs/Makefile | 1 + fs/nfs/client.c | 15 +- fs/nfs/filelayout/filelayout.c | 6 +- fs/nfs/flexfilelayout/flexfilelayout.c | 142 +++- fs/nfs/flexfilelayout/flexfilelayout.h | 2 + fs/nfs/flexfilelayout/flexfilelayoutdev.c | 6 + fs/nfs/inode.c | 57 +- fs/nfs/internal.h | 61 +- fs/nfs/localio.c | 784 ++++++++++++++++++++++ fs/nfs/nfs2xdr.c | 70 +- fs/nfs/nfs3xdr.c | 108 +-- fs/nfs/nfs4xdr.c | 84 +-- fs/nfs/nfstrace.h | 61 ++ fs/nfs/pagelist.c | 16 +- fs/nfs/pnfs_nfs.c | 2 +- fs/nfs/write.c | 12 +- fs/nfs_common/Makefile | 5 + fs/nfs_common/common.c | 134 ++++ fs/nfs_common/nfslocalio.c | 194 ++++++ fs/nfsd/Kconfig | 15 + fs/nfsd/Makefile | 1 + fs/nfsd/export.c | 8 +- fs/nfsd/filecache.c | 90 ++- fs/nfsd/filecache.h | 5 + fs/nfsd/localio.c | 183 +++++ fs/nfsd/netns.h | 8 +- fs/nfsd/nfsctl.c | 2 +- fs/nfsd/nfsd.h | 6 +- fs/nfsd/nfsfh.c | 122 ++-- fs/nfsd/nfsfh.h | 5 + fs/nfsd/nfssvc.c | 100 ++- fs/nfsd/trace.h | 3 +- fs/nfsd/vfs.h | 10 + include/linux/nfs.h | 9 + include/linux/nfs_common.h | 17 + include/linux/nfs_fs_sb.h | 10 + include/linux/nfs_xdr.h | 20 +- include/linux/nfslocalio.h | 56 ++ include/linux/sunrpc/auth.h | 4 + include/linux/sunrpc/svc.h | 7 +- net/sunrpc/auth.c | 22 + net/sunrpc/clnt.c | 6 - net/sunrpc/svc.c | 68 +- net/sunrpc/svc_xprt.c | 2 +- net/sunrpc/svcauth_unix.c | 3 +- 48 files changed, 2434 insertions(+), 402 deletions(-) create mode 100644 Documentation/filesystems/nfs/localio.rst create mode 100644 fs/nfs/localio.c create mode 100644 fs/nfs_common/common.c create mode 100644 fs/nfs_common/nfslocalio.c create mode 100644 fs/nfsd/localio.c create mode 100644 include/linux/nfs_common.h create mode 100644 include/linux/nfslocalio.h -- 2.44.0
