[PATCH 1/2] ftrace: binary and not logical for continue test

From: Steven Rostedt
Date: Wed Sep 03 2008 - 17:48:12 EST


Peter Zijlstra provided me with a nice brown paper bag while letting me know
that I was doing a logical AND and not a binary one, making a condition
true more often than it should be.

Luckily, a false true is handled by the calling function and no harm is
done. But this needs to be fixed regardless.
