#     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: 33313a747e81 ("mm: lock newly mapped VMA which can be modified after it becomes visible")
