Re: [ros-dev] [ros-diffs] [tfaber] 69296: [KMTESTS] - Add missing OBJ_KERNEL_HANDLE - OBJ_KERNEL_HANDLE in user mode has no effect... no reason to make a define around it CORE-10207

[Thomas Faber]

Oh? I'll need to add a test for that then, thanks.

What does Windows's RTL do, then? I know in XP/2003 it might just hand
out user handles, but e.g. on Win7 that would cause verifier to
bugcheck.
