Steven Rostedt 93459c6cb9 tracing: only add splice page if entries exist ... The splice code allocates a page even when the ring buffer is empty. It detects the ring buffer being empty when it it fails to copy anything from the ring buffer into the page. This patch adds a check to see if there is anything in the ring buffer before allocating a page. Thanks to logdev for letting me trace the tracer to find this. [ Impact: speed up due to removing unnecessary allocation ] Signed-off-by: Steven Rostedt <rostedt@goodmis.org>		2009-04-29 00:23:13 -04:00
