[Qemu-devel] [PATCH 0/7] tests: virtio-9p: test request cancellation

[Greg Kurz]

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:
