Do any other file systems other than btrfs support "cp --reflink" (ie BTRFS_IOC_CLONE). I am cleaning the patches to cifs.ko to do this at least for SMB2/SMB2.1/SMB3, but I thought that at the kernel file system summit somebody mentioned other in kernel file systems that support the copy offload ioctl that cp --reflink invokes (ie BTRFS_IOC_CLONE)., -- Thanks, Steve -- To unsubscribe from this list: send the line "unsubscribe linux-cifs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
