Subject: [PATCH v4 -tip 0/3] tracing: make a snapshot feature available from
 userspace

Hi, Steven,

I updated the patch which replaces static variable 'old_tracer'.

v3->v4:
 [1/3] tracing: replace static old_tracer with trace iterator's pointer to the
       original tracer's name
        - changed to comparison between pointers instead of strcmp

(v3: https://lkml.org/lkml/2012/12/19/35)
