linux 3.19.2

/proc/sys/kernel/hotplug doesn't exist anymore ?

sh-4.2# echo /sbin/mdev > /proc/sys/kernel/hotplug
sh: /proc/sys/kernel/hotplug: No such file or directory

sh-4.2# sysctl -w kernel.hotplug=/sbin/mdev
error: "kernel.hotplug" is an unknown key

does it have to do with this ?

Finally eradicate CONFIG_HOTPLUG
Ever since commit 45f035ab9b8f ("CONFIG_HOTPLUG should be always on"),
 it has been basically impossible to build a kernel with
CONFIG_HOTPLUG turned off.
 Remove all the remaining references to it.
