No; there is a separate 30 second timer which is used for writeback thread.

But in delayed allocation, there is no risk that stale data can get revealed until we actually allocate the data blocks. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
