Subject: [PATCH v3 14/14] ext4: drop the TODO comment in ext4_es_insert_extent()
Date: Sat, 29 Nov 2025 18:32:46 +0800 [thread overview]
Message-ID: <20251129103247.686136-15-yi.zhang@huaweicloud.com> (raw)
In-Reply-To: <20251129103247.686136-1-yi.zhang@huaweicloud.com>
From: Zhang Yi <yi.zhang@huawei.com>
Now we have ext4_es_cache_extent() to cache on-disk extents instead of
ext4_es_insert_extent(), so drop the TODO comment.
