[RFC PATCH 01/11] sysctl: make some functions unstatic to access by arch/lib

From: Hajime Tazaki
Date: Tue Mar 24 2015 - 09:21:45 EST


libos (arch/lib) emulates a sysctl-like interface by a function call of
userspace by enumerating sysctl tree from sysctl_table_root. It requires
to be publicly accessible to this symbol and related functions.
