Re: [PATCH v2 6/8] chardev: add API to block use of the stdio implementation

When daemonizing QEMU it is not possible to use the stdio chardev backend because the file descriptors are connected to /dev/null. Currently the chardev checks for this scenario directly, but to decouple it from the system emulator daemonizing code, we reverse the relationship. Now the system emulator calls a helper to explicitly disable use of the stdio backend. Signed-off-by: Daniel P.
