I had tried to go a bit further and address the general issue of f*() syscalls versus unlinked files:
QEMU: http://lists.gnu.org/archive/html/qemu-devel/2016-06/msg07586.html
Linux 9p driver: https://sourceforge.net/p/v9fs/mailman/message/35175775/
I remember that some issues were then reported during review of the linux patches, and I never got bandwidth to investigate further...
But if you'd like to resurrect these threads, please do. :)
