From: Andy Adamson <andros@xxxxxxxxxx> These patches add client and server support for NFSv4.2 inter-server to server copy offload. These patches build upon Anna Schumaker's COPY Operation patches which are in turn built upon Zack Brown's VFS vfs_copy_file_range syscall. Additional functionality is added to the COPY operation past what Anna added. The COPY_NOTIFY operation is added. The first three patches change Zach Brown's vfs_copy_file_range implementation. The first two patches relax the check for only performing copy offload between files with the same mount and super block, moving that check into a helper function that can be called (e.g. BTRFS) in a file systems copy_file_range function. The third patch changes vfs_copy_file_range to call the destination file (file_out) copy_file_range f_ops proceedure instead of the file_in version. The remaining patches implement the COPY_NOTIFY operation and the inter-ssc changes to the COPY operation. One source server using NL4_NETADDR is currently supported. I used the test program from Anna's COPY operation patch set. I put this patch set out knowing it will need to be merged with Zach Brown's VFS work, Anna Schumaker's intra-ssc COPY and Peng Tao's NFS CLONE patches. Questions, comments, and other testing ideas welcome. -->Andy Andy Adamson (12): VFS: Separate cross fs check from vfs_copy_file_range BTRFS: Use VFS copy offload helper VFS SQUASH use file_out instead of file_in for copy_file_range NFS add same file check and flush source and destination for COPY NFS add inter ssc functions to nfs42proc NFS add COPY_NOTIFY operation NFSD add ca_source_server<> to COPY NFSD add COPY_NOTIFY operation NFS add ca_source_server<> to COPY NFSD generalize nfsd4_compound_state flag names NFSD: allow inter server COPY to have a STALE source server fh NFSD add nfs4 inter ssc to nfsd4_copy Olga Kornievskaia (4): NFS COPY xdr changes NFS in copy use stateid returned by copy_notify NFS always use openstateid in COPY_NOTIFY NFSD: extra stateid checking in read for interserver copy fs/btrfs/ioctl.c | 3 + fs/nfs/nfs42.h | 2 +- fs/nfs/nfs42proc.c | 238 ++++++++++++++++++++- fs/nfs/nfs42xdr.c | 213 ++++++++++++++++++- fs/nfs/nfs4_fs.h | 9 +- fs/nfs/nfs4file.c | 17 +- fs/nfs/nfs4proc.c | 8 +- fs/nfs/nfs4state.c | 2 +- fs/nfs/nfs4xdr.c | 1 + fs/nfsd/Kconfig | 10 + fs/nfsd/nfs4proc.c | 473 ++++++++++++++++++++++++++++++++++++++++-- fs/nfsd/nfs4state.c | 15 +- fs/nfsd/nfs4xdr.c | 203 +++++++++++++++++- fs/nfsd/nfsd.h | 2 + fs/nfsd/state.h | 8 + fs/nfsd/xdr4.h | 29 ++- fs/read_write.c | 38 ++-- include/linux/fs.h | 1 + include/linux/nfs4.h | 7 + include/linux/nfs4intercopy.h | 39 ++++ include/linux/nfs_fs_sb.h | 1 + include/linux/nfs_xdr.h | 28 +++ 22 files changed, 1282 insertions(+), 65 deletions(-) create mode 100644 include/linux/nfs4intercopy.h -- 1.8.3.1 -- 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
