( In addition to previously posted first 8 patches, I'm sending 5 more as an
RFC for people to get the general gist of where this work heading and what
uprobe performance is now achievable. I think first 8 patches are ready to be
applied and I'd appreciate early feedback on the remaining 5 ones.

I didn't read the "RFC" patches yet, will try to do on weekend.

As for 1-8, I failed to find any problem:

Great, thanks a lot for all the thorough reviews you've provided (and
hopefully will keep providing ;).

Peter, if you don't see any problems with first 8 patches, could you
please apply them to tip/perf/core some time soon, so that subsequent
work (SRCU+timeout and, separately, lockless VMA->inode->uprobe
lookup) can be split into independent pieces and reviewed/landed
separately? Thanks!

If there are no concerns about the first 8 patches (and Oleg doesn't
have any), it would be nice to apply them. The remaining two sets of
changes are parallelizable in terms of discussion and landing them
independently, so it would help to move the uprobe optimizations works
along nicely. Thank you!
