One Line Summary

Abstract

Some layers of the file system and storage stack have the ability to efficiently copy data. btrfs and ocfs2 have file-system specific ioctl()s and implementations. Version 4.2 of the NFS protocol adds a file copying operation. SCSI has a few copy offloading methods that are in use in the field. This talk explores how we should offer a common subset of these features with a generic system call interface.
