Actually, I still very much do not like using M_NOWAIT needlessly. I would
much rather the solution for make_dev() be that the 1 or 2 places that need
to do it with a mutex held instead queue a task to do the actual make_dev()
in a taskqueue when no locks are held. This is basically what
destroy_dev_sched() is doing. Perhaps a make_dev_sched() with a similar
callback to be called on completion would be better. Having a device driver
do all the work to setup the hardware only to fail to create a node in /dev
so that userland can actually use it is pretty rediculous and useless.
It's a lot easier for me to handle a failure of make_dev in CAM than it
is to decouple the call to it. Please don't dictate policy.
