Hello everyone! Here's my current attempt at the most basic system call interface for offloading copying between files. The system call and vfs function are relatively light wrappers around the file_operation method that does the heavy lifting. There was interest at LSF in getting the basic infrastructure merged before worrying about adding behavioural flags and more complicated implementations. This series only offers a refactoring of the btrfs clone ioctl as an example of an implementation of the file copy_file_range method. I've added support for copy_file_range() to xfs_io in xfsprogs and have the start of an xfstest that tests the system call. I'll send those to fstests@. So how does this look? Do we want to merge this and let the NFS and block XCOPY patches add their changes when they're ready? - z -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
