ocfs2: Refuse to enable ocfs2 format for another filesystem
It is possible to issue Q_QUOTAON quotactl(2) e.g. for ext4 filesystem
requesting to enable quota using ocfs2 quota format. With suitable
passed arguments this can get upto ocfs2_local_check_quota_file() where
the passed superblock is from the ext4 filesystem and that can cause all
sorts of interesting things, most likely crashes. As ocfs2 quotas are
specific to ocfs2 filesystem, verify we are indeed enabling quotas
there.
