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.
