I dont have any objections to Oleg's changes. However as Oleg has said,
they are currently untested. Once the tracing and perf bits are in -tip,
I will add these bits and test them and let you know.
Given that I have tested the current bits in -tip several times, I think
it might be worthwhile to keep these changes on hold till the current
uprobe bits in -tip go upstream.
Oleg: Would this be acceptable?
