mainline inclusion from mainline-v6.17-rc1 commit f0374d80711adf8628bdd442131c045c64a10951 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/ICN2MB Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... -------------------------------- 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.
