When user space detects an error or does not receive response for a request, Lets do a reset(LDAR) is triggered. Before LDAR, user space sends flush command to the kernel space. To debug the cause for this situation and to dump the information, user space sends a dump command to the kernel space before sending flush. As a part of this command, it passes the culprit request id and the buffer into which the information can be dumped. Kernel space traverses across the drivers and find the culprit hw and dumps the relevant information in the buffer. This data is written to a file for offline processing. This commit implements the framework for traversal across the RT and NRT devices.
