Subject: [PATCH 14/23] riscv/hugetlb: pte_alloc_huge() pte_offset_huge()
Date: Tue, 9 May 2023 21:59:57 -0700 (PDT) [thread overview]
Message-ID: <d1e54510-9ea2-edf-3851-fa7635ce1e5e@google.com> (raw)
In-Reply-To: <77a5d8c-406b-7068-4f17-23b7ac53bc83@google.com>
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().
