Subject: [PATCH v4 2/9] xfs: make the seq argument to xfs_bmapi_convert_delalloc() optional
Date: Wed, 20 Mar 2024 19:05:41 +0800	[thread overview]
Message-ID: <20240320110548.2200662-3-yi.zhang@huaweicloud.com> (raw)
In-Reply-To: <20240320110548.2200662-1-yi.zhang@huaweicloud.com>

From: Zhang Yi <yi.zhang@huawei.com>

Allow callers to pass a NULLL seq argument if they don't care about
the fork sequence number.
