Steve French f19e84df37 [CIFS] Do not use btrfs refcopy ioctl for SMB2 copy offload ... Change cifs.ko to using CIFS_IOCTL_COPYCHUNK instead of BTRFS_IOC_CLONE to avoid confusion about whether copy-on-write is required or optional for this operation. SMB2/SMB3 copyoffload had used the BTRFS_IOC_CLONE ioctl since they both speed up copy by offloading the copy rather than passing many read and write requests back and forth and both have identical syntax (passing file handles), but for SMB2/SMB3 CopyChunk the server is not required to use copy-on-write to make a copy of the file (although some do), and Christoph has commented that since CopyChunk does not require copy-on-write we should not reuse BTRFS_IOC_CLONE. This patch renames the ioctl to use a cifs specific IOCTL CIFS_IOCTL_COPYCHUNK. This ioctl is particularly important for SMB2/SMB3 since large file copy over the network otherwise can be very slow, and with this is often more than 100 times faster putting less load on server and client. Note that if a copy syscall is ever introduced, depending on its requirements/format it could end up using one of the other three methods that CIFS/SMB2/SMB3 can do for copy offload, but this method is particularly useful for file copy and broadly supported (not just by Samba server).
