From f0374d80711adf8628bdd442131c045c64a10951 Mon Sep 17 00:00:00 2001 From: Baokun Li Date: Mon, 14 Jul 2025 21:03:13 +0800 Subject: [PATCH] ext4: remove unnecessary s_mb_last_start Since stream allocation does not use ac->ac_f_ex.fe_start, it is set to -1 by default, so the no longer needed sbi->s_mb_last_start is removed.
