Message-Id: <20230228114306.3328235-2-shikemeng@huaweicloud.com> Date: Tue, 28 Feb 2023 19:42:47 +0800 From: Kemeng Shi <shikemeng@...weicloud.com> To: tytso@....edu, adilger.kernel@...ger.ca, jack@...e.cz, ojaswin@...ux.ibm.com, ritesh.list@...il.com Cc: linux-ext4@...r.kernel.org, linux-kernel@...r.kernel.org, shikemeng@...weicloud.com Subject: [PATCH v2 01/20] ext4: set goal start correctly in ext4_mb_normalize_request We need to set ac_g_ex to notify the goal start used in ext4_mb_find_by_goal. Set ac_g_ex instead of ac_f_ex in ext4_mb_normalize_request.
