Subject: sched: remove binary sysctls from kernel.sched_domain
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e0361851e5647cdd62fd5c367df5d7e145769d04;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

sched: remove binary sysctls from kernel.sched_domain

kernel.sched_domain hierarchy is under CTL_UNNUMBERED and thus
unreachable to sysctl(2). Generating .ctl_number's in such situation is
not useful.
