From d9b8396a52b4e857263eeb9e1eba474ea11c19bf Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 13 Feb 2014 17:16:10 +0100 Subject: cfg80211: document sched_scan_stop synchronous behaviour Due to userspace assumptions, the sched_scan_stop operation must be synchronous, i.e. once it returns a new scheduled scan must be able to start immediately. Document this in the API.
