Subject: [PATCH 0/2] uprobes: pre-filtering
Date: Fri, 28 Dec 2012 19:12:52 +0100 [thread overview]
Message-ID: <20121228181252.GA6120@redhat.com> (raw)
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.
