This extends debugfs to make it very simple to add per cpu counters statistics that are exported there. This is useful for all kind of debugging situations. The counters have very little overhead and are simpler to use than trace points. This is the infrastructure for debugfs and a demo application to instrument the dcache RCU which I developed some time ago to track down some problems there. Posting here also so that Fengguang can use it. Module support is still missing, but could be added without too much work. -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
