From: Fengnan Chang <changfengnan@vivo.com> stable inclusion from stable-v5.10.110 commit 1c4d94e4f0b14a5a5cdf558e22af490aacb6a766 bugzilla: https://gitee.com/openeuler/kernel/issues/I574AL Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 7eab7a6968278c735b1ca6387056a408f7960265 ] when we overwrite the whole page in cluster, we don't need read original data before write, because after write_end(), writepages() can help to load left data in that cluster.
