Copy system calls came up during Plumbers a while ago, mostly because several filesystems (including NFS and XFS) are currently working on copy acceleration implementations. We haven't heard from Zach Brown in a while, so I volunteered to push his patches upstream so individual filesystems don't need to keep writing their own ioctls. Changes in v9: - Update syscall number for sys_mlock2() - Fix calls to rw_verify_area() Thanks, Anna Anna Schumaker (1): vfs: Add vfs_copy_file_range() support for pagecache copies Zach Brown (3): vfs: add copy_file_range syscall and vfs helper x86: add sys_copy_file_range to syscall tables btrfs: add .copy_file_range file operation arch/x86/entry/syscalls/syscall_32.tbl | 1 + arch/x86/entry/syscalls/syscall_64.tbl | 1 + fs/btrfs/ctree.h | 3 + fs/btrfs/file.c | 1 + fs/btrfs/ioctl.c | 91 ++++++++++++++---------- fs/read_write.c | 125 +++++++++++++++++++++++++++++++++ include/linux/fs.h | 3 + include/linux/syscalls.h | 3 + include/uapi/asm-generic/unistd.h | 4 +- kernel/sys_ni.c | 1 + 10 files changed, 193 insertions(+), 40 deletions(-) -- 2.6.2 -- To unsubscribe from this list: send the line "unsubscribe linux-api" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
