Re: [PATCH 14/23] riscv/hugetlb: pte_alloc_huge() pte_offset_huge()

Hi Hugh,

On 5/10/23 06:59, Hugh Dickins wrote:
pte_alloc_map() expects to be followed by pte_unmap(), but hugetlb omits
that: to keep balance in future, use the recently added pte_alloc_huge()
instead; with pte_offset_huge() a better name for pte_offset_kernel().
