MODVERSIONS is completely broken?


Hi,

As a test, built a kernel using 3.18.26 with a given .config file to create a .deb package. Then did the same for 3.18.27. Now, installed both header files. Built a module (the same one) for 3.18.26, tried to load it on the built 3.18.26 kernel, no problem. Try it on the 3.18.27 version, versions disagree about module_layout. I then did a diff on the difference between 3.18.26 and 3.18.27 (not many) and looked for any structure changes to any of the items as part of module_layout. NOTHING! So why would the crc be different between versions, the whole purpose of MODVERSIONS (which is a good one) is so a module can run on different versions which use the same structure layout. Did somebody break it?

TIA!!
