From e74da5235cec6cb71eb338c987f876ecc793138b Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Wed, 4 Mar 2009 20:31:11 -0500 Subject: [PATCH] tracing: fix seq read from trace files The buffer used by trace_seq was updated incorrectly. Instead of consuming what was actually read, it consumed the rest of the buffer on reads.
