Subject: [V9fs-developer] [RFC] we should solve create-unlink-getattr idiom

Hi Eric and Greg,

I encountered the similar problem with create-unlink-getattr idiom.
I use the testcase that create-unlink-setattr idiom, and I see the
bug is reported at https://bugs.launchpad.net/qemu/+bug/1336794.
Then I also see you already fix the issue and push the patch to upstream.
https://github.com/ericvh/linux/commit/eaf70223eac094291169f5a6de580351890162a2
http://patchwork.ozlabs.org/patch/626194/

Unfortunately, the two patches are not merged into master, I don't know
the reason, so I suggest if the patche can be merged into master, and
it will solve the create-unlink-getattr idiom.

Thanks,
Yiwen
