From 2f064a59a11ff9bc22e52e9678bc601404c7cb34 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Fri, 11 Jun 2021 10:28:17 +0200 Subject: sched: Change task_struct::state Change the type and name of task_struct::state. Drop the volatile and shrink it to an 'unsigned int'. Rename it in order to find all uses such that we can use READ_ONCE/WRITE_ONCE as appropriate.
