Subject: [PATCH v2 1/2] trace_uprobe: Use %lx to display offset
Date: Thu, 15 Mar 2018 13:57:55 +0530	[thread overview]
Message-ID: <20180315082756.9050-1-ravi.bangoria@linux.vnet.ibm.com> (raw)

tu->offset is unsigned long, not a pointer, thus %lx should
be used to print it, not the %px.

Fixes: 0e4d819d0893 ("trace_uprobe: Display correct offset in uprobe_events")
Suggested-by: Kees Cook <keescook@chromium.org>
Signed-off-by: Ravi Bangoria <ravi.bangoria@linux.vnet.ibm.com>
