From 8b24b2025fb4ae9bd6102bb054bd23987c35387e Mon Sep 17 00:00:00 2001 From: Likhitha Korrapati Date: Fri, 16 Jun 2023 17:25:19 +0530 Subject: [PATCH 12/30] ppc64: Remove redundant PTE checks Remove redundant checks for PTE (Page Table Entry) because those conditions are already covered. if (!(pte & _PAGE_PRESENT)) { ... return FALSE; } if (!pte) return FALSE; The second pte check is redundant because it holds true only when pte is 0. If pte is 0 then (!(pte & _PAGE_PRESENT)) is true and it will return false. So there is no need for one more pte check.
