Subject: [PATCH] reiserfs: fix uninit-value in reiserfs_new_inode
Date: Sun, 31 Dec 2023 09:04:04 +0800 [thread overview]
Message-ID: <tencent_897491761D662E3D7336B297BA37064A7C09@qq.com> (raw)
In-Reply-To: <000000000000da757a060d58ebbe@google.com>
Before creating a new inode, it is necessary to initialize the "new packing
locality" tag of the dir.
