Subject: [PATCH v2 3/6] ext4: remove unnessary size check in ext4_xattr_inode_get()
Date: Wed,  7 Dec 2022 15:40:40 +0800	[thread overview]
Message-ID: <20221207074043.1286731-4-yebin@huaweicloud.com> (raw)
In-Reply-To: <20221207074043.1286731-1-yebin@huaweicloud.com>

From: Ye Bin <yebin10@huawei.com>

As previous patch add check in ext4_xattr_check_entries(), before call
ext4_xattr_inode_get() will already do xattr entries check.
