hulk inclusion category: bugfix bugzilla: 186737, https://gitee.com/openeuler/kernel/issues/I58COJ CVE: NA -------------------------------- We have already check the io_error and uptodate flag before submitting the superblock buffer, and re-set the uptodate flag if it has been failed to write out. But it was lockless and could be raced by another ext4_commit_super(), and finally trigger '!uptodate' WARNING when marking buffer dirty. Fix it by submit buffer directly.
