If anyone has any objections, please let me know. ------------------ From: Dmitry Antipov [ Upstream commit a2b1c419ff72ec62ff5831684e30cd1d4f0b09ee ] In 'ocfs2_validate_inode_block()', add an extra check whether an inode with inline data (i.e. self-contained) has no clusters, thus preventing an invalid inode from being passed to 'ocfs2_evict_inode()' and below.
