This is really a core kernel struct in disguise until we can finally place it in kernel/. There is an immediate need for a fence collection mechanism that is more flexible than fence-array, in particular being able to easily drive request submission via events (and not just interrupt driven). The same mechanism would be useful for handling nonblocking and asynchronous atomic modesets, parallel execution and more, but for the time being just create a local sw fence for execbuf.
