From 76f0d07376388f32698ba51b6090a26b90c1342f Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Fri, 4 Sep 2009 12:12:39 -0400 Subject: tracing: remove users of tracing_reset The function tracing_reset is deprecated for outside use of trace.c. The new function to reset the the buffers is tracing_reset_online_cpus. The reason for this is that resetting the buffers while the event trace points are active can corrupt the buffers, because they may be writing at the time of reset. The tracing_reset_online_cpus disables writes and waits for current writers to finish. This patch replaces all users of tracing_reset except for the latency tracers. Those changes require more work and will be removed in the following patches.
