From ce4dd4429b3c7e4506870796f3b8b06d707d2928 Mon Sep 17 00:00:00 2001 From: David Howells Date: Wed, 16 Oct 2019 15:13:41 +0100 Subject: Remove the nr_exclusive argument from __wake_up_sync_key() Remove the nr_exclusive argument from __wake_up_sync_key() and derived functions as everything seems to set it to 1. Note also that if it wasn't set to 1, it would clear WF_SYNC anyway.
