=====================================
Normally, a stripped down copy of a module's symbol table (containing only
"core" symbols) is made available through module->symtab (See layout_symtab()
-in kernel/module.c). For livepatch modules, the symbol table copied into memory
-on module load must be exactly the same as the symbol table produced when the
-patch module was compiled. This is because the relocations in each livepatch
-relocation section refer to their respective symbols with their symbol indices,
-and the original symbol indices (and thus the symtab ordering) must be
+in kernel/module/kallsyms.c). For livepatch modules, the symbol table copied
+into memory on module load must be exactly the same as the symbol table produced
+when the patch module was compiled. This is because the relocations in each
+livepatch relocation section refer to their respective symbols with their symbol
+indices, and the original symbol indices (and thus the symtab ordering) must be
preserved in order for apply_relocate_add() to find the right symbol.
For example, take this particular rela from a livepatch module:::
