From: Paolo 'Blaisorblade' Giarrusso <[email protected]>
An UML user reported (against 2.6.13.3/UML) he got kernel Oopses when trying to
rmmod (on a kernel with module unloading enabled) a module compiled with module
unloading disabled. As crashing is a very correct thing to do in that case, a
solution is altering the vermagic string to include this too.
Possibly, however, the code should not crash in this case, even if the module
didn't support unloading - it should simply abort the module removal. In this case,
fixing that bug would be a better solution. I've not investigated though.
Thanks to Hayim for reporting.
