revert "mm: make sure all file VMAs have ->vm_ops set"
Revert commit 6dc296e7df4c "mm: make sure all file VMAs have ->vm_ops set". Will Deacon reports that it "causes some mmap regressions in LTP, which appears to use a MAP_PRIVATE mmap of /dev/zero as a way to get anonymous pages in some of its tests (specifically mmap10 [1])". William Shuman reports Oracle crashes. So revert the patch while we work out what to do. Reported-by: William Shuman <wshuman3@gmail.com> Reported-by: Will Deacon <will.deacon@arm.com> Cc: Kirill A.
