Agreed.

I do plan to be uploading stable updates for 2.6.35.x that include the
changes that got pulled for 2.6.35-rc1, and I'll update 2.6.34 and
2.6.32, as well, with 2.6.34 including the updates that somehow didn't
all make it to stable last time.  (I'm thinking about also including
an ftp upload since for some reason some mail server between me at
stable@...nel.org seems to be dropping mail messages when they get
blasted out using git send-email.  :-/ )

I'm at Linuxcon this week though, so I probably won't get to it until
sometime next week.
