Is there any specific reason to require the external bitmap to be on a file? Currently the code requires regular files to call bmap on them, which is a fairly dangerous thing to start with. But why don't we just allow using block devices to store the bitmap directly? -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
