Sorry these took a while! This version moves the new tracepoints closer
to the vfs layer, into the non-version specific common vfs helpers.
I've also made separate patches that remove the dprintks. Since the new
tracepoints aren't in the same places as the old dprintk's, there could
be an argument for keeping them. I'm fine with either.

Changes in v2:
- Break tracepoints out into multiple patches
