As I said in my other posting, I believe Chuck's changes are relatively
orthogonal to what you want to do: they neither make the low-level
plumbing better or worse for readv()/writev().
We'd be happy to work with you in the run-up to 2.6.18 to add
multi-segment support for the existing patchsets. It makes more sense to
me to append that functionality to the existing patchsets rather than
trigger a complete rewrite (and thus have a sh_tload more code to
retest).
after i reviewed this work with zach last summer, he and i also agreed
that it would be best if i did this work after the generic changes are
integrated -- so he wouldn't have to work on, and possibly break, the
NFS client.
i have been watching the multi-segment iovec work since then, and fully
intended to add the support for readv/writev aio in the NFS direct path
when the generic support becomes available.
