Primiano Tucci cd452300a7 Allow tracing service to access kallsyms on userdebug ... This CL allows the traced_probes service to temporarily lower kptr_restrict and read /proc/kallsyms. This is allowed only on userdebug/eng builds. The lowering of kptr_restrict is done via an init property because the kernel checks that the kptr_restrict writer is CAP_SYS_ADMIN, regardless of the /proc file ACLs [1].
