+ tristate "Log writes target support"
+ depends on BLK_DEV_DM
+ ---help---
+ This device-mapper target takes two devices, one device to use
+ normally, one to log all write operations done to the first device.
+ This is for use by file system developers wishing to verify that
+ their fs is writing a consitent file system at all times by allowing
+ them to replay the log in a variety of ways and to check the
+ contents.
+
+ To compile this code as a module, choose M here: the module will
+ be called dm-log-writes.
