Subject: [PATCH 2/3] trace_kprobes: always show group name
Date: Wed, 25 Nov 2009 16:32:47 +0800 [thread overview]
Message-ID: <4B0CEBAF.6000104@cn.fujitsu.com> (raw)
Sometimes the group name is not "kprobes",
It'll be better if we can read it from tracing/kprobe_events.
# echo 'r:laijs/vfs_read vfs_read %ax' > kprobe_events
# cat kprobe_events
r:laijs/vfs_read vfs_read %ax=%ax
