From 84e8e54e2ed9d857c4e10a7e487532203385249c Mon Sep 17 00:00:00 2001 From: Ying Sun Date: Wed, 6 Sep 2023 12:50:12 +0800 Subject: mm/shmem: remove dead code can not be satisfied by "(CONFIG_SHMEM)&&(!(CONFIG_SHMEM))" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The value of “.fs_flags” in line 4608 is a dead code which will never be implemented，because its conditions of line 47 "#ifdef CONFIG_SHMEM" and line 4607 are mutually exclusive. It is recommended to delete redundant code.
