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
