Vasiliy Kovalev 5f86e79c0b ovl: Filter invalid inodes with missing lookup function ... commit c8b359dddb upstream. Add a check to the ovl_dentry_weird() function to prevent the processing of directory inodes that lack the lookup function. This is important because such inodes can cause errors in overlayfs when passed to the lowerstack.
