unresearched question/suggestion: Is there general support for a "fast copy" ioctl in the VFS layer, which would be hooked by file systems that support COW or other forms of deduplication and can provide copy semantics by manipulating metadata only? -- "It is merely a matter of persistence." -- Albert Camus -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
