Currently, large folio swap-in is supported, but we lack a method to analyze their success ratio. Similar to anon_fault_fallback, we introduce per-order mTHP swpin_fallback and swpin_fallback_charge counters for calculating their success ratio. The new counters are located at: /sys/kernel/mm/transparent_hugepage/hugepages-<size>/stats/ swpin_fallback swpin_fallback_charge Link: https://lkml.kernel.org/r/20241202124730.2407037-1-haowenchao22@gmail.com Signed-off-by: Wenchao Hao <haowenchao22@gmail.com> Reviewed-by: Barry Song <baohua@kernel.org> Reviewed-by: Lance Yang <ioworker0@gmail.com> Cc: Baolin Wang <baolin.wang@linux.alibaba.com> Cc: David Hildenbrand <david@redhat.com> Cc: Jonathan Corbet <corbet@lwn.net> Cc: Matthew Wilcox <willy@infradead.org> Cc: Peter Xu <peterx@redhat.com> Cc: Ryan Roberts <ryan.roberts@arm.com> Cc: Usama Arif <usamaarif642@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> |
