The latter clears the invalidated bit of a partial pages rather than discarding it entirely. This causes copy_file_range() to fail on cifs because the partial pages at either end of the destination range aren't evicted and reread, but rather just partly cleared. This causes generic/075 and generic/112 xfstests to fail.
