Subject: Re: [PATCH v6 07/31] ext4: allow ext4_map_blocks() to start its own transaction handle
Date: Thu, 03 Sep 2026 13:02:24 +0000 [thread overview]
Message-ID: <20260903130224.9F0E21F00A3A@smtp.kernel.org> (raw)
In-Reply-To: <20260903123543.2302999-8-yi.zhang@huaweicloud.com>
> From: Zhang Yi <yi.zhang@huawei.com>
>
> Make ext4_map_blocks() start its own transaction handle when the caller
> does not provide one. The handle is started after the lookup path
> confirms that allocation is actually needed, and is stopped at the
> unified out_handle exit path. This avoids unnecessarily starting a
> handle for pure mapping queries. This prepares for the buffered iomap
> writeback conversion, which improves performance for fragile overwrite
> cases.
