From 4823ed7eadf35e4b57ce581327e21d39585f1f32 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Mon, 12 May 2008 21:21:01 +0200 Subject: [PATCH] ftrace: fix setting of pos in read_pipe In resetting the iterator in read_pipe, the reset of pos was postitioned in the wrong location with respect to the memset operation. The current code sets pos, incorrectly, to zero.
