If we are going to use this slot for fence fd, may as well make it
supply both before/after.
Not sure what you mean by before/after?
In the future it will take in the input fence fd and return the output fence
if that's what you mean.
BTW, couldn't we take 32bits here and leave 32bits reserved?
I guess so. Any ideas why the same wasn't done with rsvd1 - I see only
32-bits are used for context id there?
