Are you getting some error or the symbol is not exported after rebooting to the recompiled kernel ? The hex string before symbol in ksyms is actually the memory address (virtual) of where it is located and the string after symbol name like _Rxxxxx is the version related to that symbol for the running compiled kernel (and I saw this _Rxxxxx different on different machines having the same kernel with same configuration options) (CMIIW) If your symbol exists/exported in ksyms (with any other string appended to it) then you can access it directly in you module, might need to redefine is with extern for removing compilation warning ! -- Fawad Lateef -- Kernelnewbies: Help each other learn about the Linux kernel.
