Subject: [PATCH 22/24] use original reloc for symbols exported from modules
|
||
|
|
|
||
|
|
symbols exported in a patch will generate a symbol version with
|
||
|
|
object module name in Module.symvers, but the symbol is actually
|
||
|
|
in patch module which cause livepatch symbol lookup failed.
