[PATCH i-g-t 3/5] gem_wsim: Remove some unused struct members

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

We do not bother explicitly unmapping memory on exit so no need to store
address and size in the workload step struct.

No, we don't filter what the kernel gets, not in the ioctl wrapper
itself.

You only need to do it for

ww->bb_sz = ALIGN(get_bb_sz(), 4096);

All batch lengths are start = ww->bb_sz - get_bb_sz() and so remain
correct. Right?

If compiler happy, and I'm happy about leaving the mmap dangling for the
kernel to clean up,

If compiler happy, and I'm happy about leaving the mmap dangling for the
kernel to clean up,

Have we not snuck -lrt into the core library yet, pretty sure libigt.la
now includes clock_gettime() and so must be pulling it in already?

i.e. can we just drop the above line?

I know, but I could flip a coin on these kind of decisions. (Sometimes 
we open code for such ABI tests.) Move it to non-double underscore flavours?

I think so. I have one more assignment site of w->bb_sz in the upcoming 
code so it was 2 : 2 and I flipped a coin. Actually I wanted to make it 
explicit what I am fixing - the mmap size. But now you'll say batch size 
is also implicitly rounded.. oh well.. I prefer the explicit round up at 
mmap time.
