With async INIT this is possible by waiting until the write(2) syscall
for the INIT reply returns.  This is because the initialization is
performed within the context of the write call.

For sync INIT the initialization is performed in the context of the
mount/FSCONFIG_CMD_CREATE, libfuse can wait until the respective
syscall returns.

So yes, it's possible to ensure this from userspace, no kernel change is need.
