Date: Fri, 4 Sep 2015 11:02:35 +0200 From: David Herrmann <dh.herrmann@...il.com> To: linux-kernel@...r.kernel.org Cc: Greg KH <gregkh@...uxfoundation.org>, Daniel Mack <daniel@...que.org>, tixxdz@...ndz.org, David Herrmann <dh.herrmann@...il.com> Subject: [PATCH] kdbus: raise hard-coded limit of matches The current MATCH limit is far too low. We allow more bus-connections per user than peers to install matches. Raise the limit to a reasonable default of 4096. The current limit is exactly enough to run Gnome, but can be easily exceeded by starting some additional service providers. With the raised limit, we should be fine for the near future. Some day, we might decide to make those limits dynamically configurable. However, that needs some more benchmarking, until we can figure out perfect defaults.
