A kernel was released that changed how the hash value got computed for casefolded filenames. (used for better windows compatibility) That kernel then went into production. This unfortunately split some file-systems that supported this into two incompatible versions, breaking the kernel rule 1.

There might now exist file-systems were created/modified with this bug present that the old/fixed kernels can't understand.
