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
