Re: Default number of active kretprobes
By the way, regarding the problem of underestimating maxactive, we
briefly considered the idea of having a system-wide pool of
kretprobe_instances to draw on in case any particular kretprobe runs
short. But that adds a little more complexity to the implementation and
to the user interface. (Presumably, the pool size would be a
configuration option.)
It shouldn't be too tough to prototype that -- probably just adjust
get_free_rp_inst() and recycle_rp_inst().
