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.
