Yes please, integrate all fixups. You may choose to track those fixups the way I do: [avagin@google.com: fix lock leak in mfill_get_vma()] Link: https://lkml.kernel.org/r/20260316173829.1126728-1-avagin@google.com [akpm@linux-foundation.org: update mfill_copy_folio_retry()] Link: https://lkml.kernel.org/r/20260316173829.1126728-1-avagin@google.com Link: https://lkml.kernel.org/r/20260306171815.3160826-6-rppt@kernel.org Signed-off-by: Mike Rapoport (Microsoft) Signed-off-by: Andrei Vagin Cc: Andrea Arcangeli Cc: Axel Rasmussen ...
