Subject: Re: [PATCH v2 00/10] Performance fixes for 9p filesystem

Well timed prompt, sorry — I had been out of pocket while traveling.  The WIPs in the development branch on GitHub are me working my way through the dir-cache patches (which was intended as the next set of patches after this one) — but those are complimentary to this set, so I’m about send out a [V3] without those so we can get this into linux-next with enough time for some more exhaustive testing before the next merge window.

I’m fine with funneling these through Dominique since he’s currently the active maintainer, but I’ve also re-established kernel.org <http://kernel.org/> credentials so I can field the pull-request if desired.
