From: Li Lingfeng <lilingfeng3@huawei.com> hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7FI78 -------------------------------- This reverts commit 90d1a836f017faf27c24265773171997485075ce. It's not proper to just abort IO when the map is not ready. So revert this and requeue IO to keep consistent with the community.
