sys/kern kern_conf.c
Log:
MFC part of the rev. 1.210, and the rev. 1.211.
In the giant_XXX wrappers for the device methods of the D_NEEDGIANT
drivers, do not dereference the cdev->si_devsw. It is racing with
the destroy_devl() clearing of the si_devsw. Instead, use the
dev_refthread() and return ENXIO for the destroyed device.
