Subject: [PATCHv3 0/3] Fix crash due to vma_is_anonymous() false-positives

Fix crash found by syzkaller.

Build on top of Linus' changes in 4.18-rc6.

Andrew, could you please drop mm-drop-unneeded-vm_ops-checks-v2.patch for
now. Infiniband drivers have to be fixed first.

Kirill A. Shutemov (3):
  mm: Introduce vma_init()
  mm: Use vma_init() to initialize VMAs on stack and data segments
  mm: Fix vma_is_anonymous() false-positives
