Abstract
A transaction device driver that exports a transaction interface tailored to the requirements of conventional journaling file systems. The operating system file system informs the transaction device driver when a file system operation begins and ends and also informs the transaction driver about important data updates which have occurred since the beginning of the file system operation. The transaction device driver logs the updates as the data appears through the normal read/write/strategy entry points into the driver and, should the system fail while there are outstanding operations, ensures that either all of the changes for the operation will appear in the file system or that none of the changes will appear.
