[PATCH 0/2] uprobes: pre-filtering

[Oleg Nesterov]

Hello.

On top of preparations I sent a month ago. Srikar, you still didn't
review the last 2 patches. I assume you do not care so I am going to
add them without your ack.

Initially I was going to send more patches in this series. We can add
some optimizations to avoid the unnecessary register_for_each_vma() or
even consumer->filter() if there is a consumer with ->filter == NULL.
But lets do this later, lets discuss the functional change first.

Next steps:

	- teach handler_chain() to remove the unwanted breakpoints

	- if the above is not enough, implement UPROBE_FILTER_FORK

	- implement uprobe_apply(consumer, task, is_register) ?

Ole.
