From 75b8e98263fdb0bfbdeba60d4db463259f1fe8a2 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Thu, 3 Feb 2011 23:25:46 -0500 Subject: [PATCH] tracing/filter: Swap entire filter of events When creating a new filter, instead of allocating the filter to the event call first and then processing the filter, it is easier to process a temporary filter and then just swap it with the call filter. By doing this, it simplifies the code. A filter is allocated and processed, when it is done, it is swapped with the call filter, synchronize_sched() is called to make sure all callers are done with the old filter (filters are called with premption disabled), and then the old filter is freed.
