[PATCH v5 08/25] mm: Remove pte_next_pfn() and replace with pte_advance_pfn()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Now that the architectures are converted over to pte_advance_pfn(), we
can remove the pte_next_pfn() wrapper and convert the callers to call
pte_advance_pfn().
