Hi guys,
we are using qemu to create some sandboxes and use virtiofs to share some
folders between the host and the guest. This is the command that we start the
virtiofsd
`virtiofsd --syslog -o cache=auto -o no_posix_lock -o source={some path} --fd=3
-f --thread-pool-size=1`
We find out that with such settings, when we creating some file inside guest
and then delete those file in the host. The disk space will not be freed until
we run the `rm {file}` inside guest again and guest will report `no such file
or directory` but the space is freed.
We also find out that once we change the option to `cache=none`, this wierd
behavior disappears.
Is this expected. Is there a way that we can enable the cache while make the
scenario that I mentioned above work?
