Currently, when a user is subscribing for binding table publications, he will receive a PUBLISH event for all already existing matching items in the binding table. However, a group socket making a subscriptions doesn't need this initial status update from the binding table, because it has already scanned it during the join operation. Worse, the multiplicatory effect of issuing mutual events for dozens or hundreds group members within a short time frame put a heavy load on the topology server, with the end result that scale out operations on a big group tend to take much longer than needed. We now add a new filter option, TIPC_SUB_NO_STATUS, for topology server subscriptions, so that this initial avalanche of events is suppressed. This change, along with the previous commit, significantly improves the range and speed of group scale out operations. We keep the new option internal for the tipc driver, at least for now.

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.
