From 36ef159f4408b08eae7f2af6d62bedd3f4343758 Mon Sep 17 00:00:00 2001 From: Qi Zheng Date: Fri, 14 Jan 2022 14:05:51 -0800 Subject: mm: remove redundant check about FAULT_FLAG_ALLOW_RETRY bit Since commit 4064b9827063 ("mm: allow VM_FAULT_RETRY for multiple times") allowed VM_FAULT_RETRY for multiple times, the FAULT_FLAG_ALLOW_RETRY bit of fault_flag will not be changed in the page fault path, so the following check is no longer needed: flags & FAULT_FLAG_ALLOW_RETRY So just remove it.
