There does not seem to be a mremap() test that would do such a thing, so
we should be safe :-).
BTW there was a similar fix for mmap() with MAP_FIXED that caused a LTP
test to fail and was fixed in:

mm/mmap: check for RLIMIT_AS before unmapping
And I haven't heard of any breakages so far so I guess that this very
similar situation and that the possibility of breaking real world
applications here is really low.
