From f0baa040f7a597fb099bf652c754b1a8a9e183f7 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Thu, 15 Mar 2018 11:42:06 +0100 Subject: sched/wait, drivers/media: Convert wait_on_atomic_t() usage to the new wait_var_event() API The old wait_on_atomic_t() is going to get removed, use the more flexible wait_var_event() API instead. Unlike wake_up_atomic_t(), wake_up_var() will issue the wakeup even if the variable is not 0. No change in functionality.
