Apparent race between reiser4 and direct migration patches in 16-rc1- mm4. Direct migration added arg to rmap.c:try_to_unmap()--int ignore_refs-- and fixed up existing refs. reiser4 adds new call with single arg.
One doesn't see this when building mm4 w/ reiser4 because the ref under an "#if REISER4_COPY_ON_CAPTURE" that is apparently not enabled. I just noticed it while looking at direct migration patches. So, this patch is essentially UNTESTED. Supplied simply to illustrate the location of the single arg ref.
