Sure, at least that combination should enable kprobe-tracer forcibly.
A few further (and very small) UI tweaks i'd suggest:
Firstly, could we please make the first probe inserted named plain after
the symbol it specifies, with no _0 postfix? I.e. instead of:
7358 perfprobe:__switch_to_0 # 0.000 M/sec
7358 perfprobe:__switch_to # 0.000 M/sec
Subsequent probes for the same symbol can be named _1, _2 - but the
first symbol should not have this needless post-fix.
Ah, this prefix means the offset from the symbol. Of course we can
remove it if the offset == 0. Or, would you think make the postfix
sequence number of probes on the same symbol?
