xfs: scrub should mark a directory corrupt if any entries cannot be iget'd
mainline inclusion from mainline-v5.10-rc5 commit 4b80ac64 category: bugfix bugzilla: 187526,https://gitee.com/openeuler/kernel/issues/I4KIAO Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4b80ac64450f169bae364df631d233d66070a06e -------------------------------- It's possible that xfs_iget can return EINVAL for inodes that the inobt thinks are free, or ENOENT for inodes that look free. If this is the case, mark the directory corrupt immediately when we check ftype. Note that we already check the ftype of the '.' and '..' entries, so we can skip the iget part since we already know the inode type for '.' and we have a separate parent pointer scrubber for '..'.
