Subject: [PATCH v6 03/15] ubifs: Fix wrong number of inodes locked by ui_mutex in ubifs_inode comment
Date: Mon, 27 Dec 2021 11:22:34 +0800 [thread overview]
Message-ID: <20211227032246.2886878-4-chengzhihao1@huawei.com> (raw)
In-Reply-To: <20211227032246.2886878-1-chengzhihao1@huawei.com>
Since 9ec64962afb1702f75b("ubifs: Implement RENAME_EXCHANGE") and
9e0a1fff8db56eaaebb("ubifs: Implement RENAME_WHITEOUT") are applied,
ubifs_rename locks and changes 4 ubifs inodes, correct the comment
for ui_mutex in ubifs_inode.
