[Qemu-devel] [PATCH v2 5/5] tests/test-vmstate.c: test array of ptr to primitive

[Halil Pasic <pasic@linux.vnet.ibm.com>]

Let's have a test for ptr arrays to some primitive type with some
not-null and null ptrs intermixed.

Signed-off-by: Halil Pasic <pasic@linux.vnet.ibm.com>

Mainly for the sake of completeness and also to demonstrate that it works
since in the previous version I wrongly stated it does not. If guys think
we do not need this, I'm happy with just dropping it.
