- Only print debug message when failed to serach for kernel symbol from /proc/kallsyms
-
- Kernel symbol page_offset_base could be unavailable when mm KASLR code is
- not compiled in kernel. It's inappropriate to print out error message
- when failed to search for page_offset_base from /proc/kallsyms. Seems now
- there is not a way to find out if mm KASLR is compiled in or not. An
- alternative approach is only printing out debug message in get_kernel_sym
- if failed to search a expected kernel symbol.
-
- Do it in this patch, a simple fix.
