From: Li Nan <linan122@huawei.com> mainline inclusion from mainline-v6.9-rc1 commit 91b26a39fb83cf370d94980609bf649c3c46993c category: bugfix bugzilla: https://atomgit.com/openeuler/kernel/issues/8374 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... -------------------------------- There is nothing to do at 'out' before setting 'did_set_md_closing' in md_ioctl(). Return directly, and it will help us to remove 'did_set_md_closing' later.
