[PATCH] sysctl: fix the selinux_sysctl_get_sid I goofed and when reenabling the fine grained selinux labels for sysctls and forgot to add the "/sys" prefix before consulting the policy database. When computing the same path using proc_dir_entries we got the "/sys" for free as it was part of the tree, but it isn't true for clt_table trees. Signed-off-by: Eric W.
