The fact that vDSO calls were removed out of the necessity (because having
the broken TOD stuff removed was better than to leave it in place producing
inexact results) doesn't mean that everything in the patches provided was
broken and of no use. Yet you want everything removed in favor of somewhat
dubious implementation.

There was no bypassing, everything was submitted publicly via this list.
The -rt patch (via the hrtimers patchset) was the place to merge the hrtimers
code at thiat time, and nobody showed any interest in making the code better,
i.e. amending vDSO stuff, for months... (The question also is why Tony was
submitting his patches also to linux-rt-users while they were known not to
apply to the -rt patch.)
