Subject: [PATCH v3 4/7] mm/memfd_luo: use i_size_write() to set inode size during retrieve
Date: Thu, 26 Mar 2026 16:47:24 +0800	[thread overview]
Message-ID: <20260326084727.118437-5-duanchenghao@kylinos.cn> (raw)
In-Reply-To: <20260326084727.118437-1-duanchenghao@kylinos.cn>

Use i_size_write() instead of directly assigning to inode->i_size
when restoring the memfd size in memfd_luo_retrieve(), to keep code
consistency.

No functional change intended.
