I changed the size of "struct malloc_type", which is embedded in modules 
declaring new malloc types, on 19 April, r191267.  However, I also changed 
__FreeBSD_version, which should cause updated kernels to reject older modules. 
If people are experiencing the panic, they should make sure all modules are in 
sync with their kernel.  If it still occurs, it's probably a bug in the 
module's use of malloc(9), although it may be a bug in the malloc(9) 
sanity-checking I added. :-)
