This happens because\nvmf_anon_prepare() could drop the per-VMA lock and allow the current VMA\nto be freed before hugetlb_vma_unlock_read() is called.\n\nWe can fix this by using a modified version of vmf_anon_prepare() that\ndoesn't release the VMA lock on failure, and then release it ourselves\nafter hugetlb_vma_unlock_read()."
