Subject: Re: [PATCH v12 01/13] sk_run_filter: add support for custom
load_pointer
Hi,
So far, it looks like everyone who spoke up is satisfied with this patch
series. Or their MUAs got caught up on a leap-year bug and missed the
posting. ;)
Is it time to pull this into -next so more people can feel it? I brought
Andy Lutomirski's patches forward (needed to bump the prctl values), and
updated my git tree. If we're ready, here it is in all its request-pull
format glory:
The following changes since commit 2422c8368337196594265d52cad7316c9404bfcf:
