Date: Thu, 9 Jul 2026 09:01:01 +0300

This reverts commit 58b6fcd2ab34 ("ocfs2: mark inode bad upon validation
failure during read").

Since 'make_bad_inode()' resets inode type to S_IFREG, doing this for
directory inode during active VFS lookup is likely to confuse the latter,
including VFS_BUG_ON_INODE() triggered in this case.
