Hugh Dickins 1c7873e336 mm: lock newly mapped VMA with corrected ordering
Lockdep is certainly right to complain about

  (&vma->vm_lock->lock){++++}-{3:3}, at: vma_start_write+0x2d/0x3f
                 but task is already holding lock:
  (&mapping->i_mmap_rwsem){+.+.}-{3:3}, at: mmap_region+0x4dc/0x6db

Invert those to the usual ordering.

Fixes: 33313a747e ("mm: lock newly mapped VMA which can be modified after it becomes visible")
