There are two places queuing the disco event DISCE_REVALIDATE_DOMAIN. One is in sas_porte_broadcast_rcvd() and uses sas_chain_event() to queue the event. The other is in sas_enable_revalidation() and uses sas_queue_event() to queue the event. We have diffrent work queues for event and discovery now, so the DISCE_REVALIDATE_DOMAIN event may be processed in both event queue and discovery queue. Now since we do synchronous event handling, we cannot do it in discovery queue, so have to trigger a fake broadcast event to re-trigger the revalidation from event queue.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
