trace_uprobe: Display correct offset in uprobe_events
Recently, how the pointers being printed with %p has been changed by commit ad67b74d2469 ("printk: hash addresses printed with %p"). This is causing a regression while showing offset in the uprobe_events file. Instead of %p, use %px to display offset. Before patch: # perf probe -vv -x /tmp/a.out main Opening /sys/kernel/debug/tracing//uprobe_events write=1 Writing event: p:probe_a/main /tmp/a.out:0x58c # cat /sys/kernel/debug/tracing/uprobe_events p:probe_a/main /tmp/a.out:0x0000000049a0f352 After patch: # cat /sys/kernel/debug/tracing/uprobe_events p:probe_a/main /tmp/a.out:0x000000000000058c Link: http://lkml.kernel.org/r/20180106054246.15375-1-ravi.bangoria@linux.vnet.ibm.com Cc: stable@vger.kernel.org Fixes: ad67b74d2469 ("printk: hash addresses printed with %p") Acked-by: Srikar Dronamraju <srikar@linux.vnet.ibm.com> Signed-off-by: Ravi Bangoria <ravi.bangoria@linux.vnet.ibm.com> Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
