This series does several changes to virtio-9p-test in order to be able
to test request cancellation (flush in 9p wording):
patches 1-2: preparatory work, basically doing things in the test code,
rather that in the common code for flexibility and clarity
patch 3: the cornerstone of the series, switch to using the synth fsdev
backend, which allows to associate specific write/read ops to
a given file. Since this backend never got used since it was
merged, it looks like an ideal vehicle to add QTEST aware code
in QEMU
patches 4-5: trivial open & write tests, since the flush test will need
to open a file and write to it
patch 6: another important patch that allows to know the length written
by the guest into a used buffer
patch 7: the goal of this series, two request cancellation tests
This series depends on the following patch:
