For bad handles, also try creating a valid handle and checking
for (i = 16; i < BITS_PER_TYPE(arg.handle); i++)
arg.handle = real_handle | BIT(i);
Especially with (1<<31) set as historically the idr was only a 31-bit
cyclic allocator, so might be susceptible to wraparound.

Would:
real_handle = gem_create(...);
arg.handle = real_handle + 1;
guarantee an invalid handle?

If there's only been one handle allocated, yes.

Also arg.offset = -size is a good one.
Then size=8192 and arg.offset=-4096;

Hmmm, >4096 seems not to be returning an error. Where should it be

vm_mmap() should be reporting an error if args->offset + arg->size
overflow. Or at least that is what we assumed.

But both for read. Where's the write through one mmap, check it arrives
in the second.
memcmp(ptr1, ptr2) just reduces to
memcmp(ptr1, pattern) || memcmp(ptr2, pattern)
The fault handling in the kernel is no different between those two.

**WARNING**
Minor unknown changes coming with IGTPW_2600_full need to be verified
manually.
If you think the reported changes have nothing to do with the changes
introduced in IGTPW_2600_full, please notify your bug team to allow them
to document this new failure mode, which will reduce false positives in CI.
