Hi David,

We have a series for net-next that adds support for Spectrum-2 shared
buffers and it depends on this patch. I was wondering if you could merge
net into net-next today or later this week, so that we could submit it.

Normally I would just wait for the merge to happen, but it looks like
this is going to be the last week to submit changes and I prefer not to
miss the window while waiting for the inevitable merge.

Thanks and sorry about the noise.
