Well timed prompt, sorry =E2=80=94 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) =E2=80=94 but those are complimentary to this =
set, so I=E2=80=99m 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=E2=80=99m fine with funneling these through Dominique since he=E2=80=99s=
 currently the active maintainer, but I=E2=80=99ve also re-established =
kernel.org <http://kernel.org/> credentials so I can field the =
pull-request if desired.

          -Eric
