From: Yu Kuai <yukuai3@huawei.com> mainline inclusion from mainline-v6.7-rc5 commit f2d87a759f6841a132e845e2fafdad37385ddd30 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8T02O Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... -------------------------------- Commit ac619781967b ("md: use separate work_struct for md_start_sync()") use a new sync_work to replace del_work, however, stop_sync_thread() and __md_stop_writes() was trying to wait for sync_thread to be done, hence they should switch to use sync_work as well. Noted that md_start_sync() from sync_work will grab 'reconfig_mutex', hence other contex can't held the same lock to flush work, and this will be fixed in later patches.
