/* The purpose of non-blocking forks is to avoid involving VFS in the forking
* process, because VFS may be blocked on a sendrec() to a MFS that is
* waiting for a endpoint update for a dead driver. We have just published
* that update, but VFS may still be blocked. As a result, VFS may not yet
* have received PM's fork message. Hence, if we call mapdriver5()
* immediately, VFS may not know about the process and thus refuse to add the
* driver entry. The following temporary hack works around this by forcing
* blocking communication from PM to VFS. Once VFS has been made non-blocking
* towards MFS instances, this hack and the entire fork_nb() call can go.
