X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6d76ec38721f964ae9ac65d80ef8628199986fa4;p=openwrt%2Fstaging%2Fneocturne.git

procd: support generic mount triggers and clean up

Allow init scripts to trigger free-form actions by exposing
procd_add_action_mount_trigger.
Clean up mount trigger wrappers while at it to reduce code duplication.
