From 71aa11a40d1a1d80196b55d8dd95be2bc4c1649e Mon Sep 17 00:00:00 2001 From: Sebastian Ott Date: Tue, 12 Jun 2018 13:56:21 +0200 Subject: [PATCH] s390/css: start the subchannel evaluation earlier The css bus code uses 2 initcalls: channel_subsystem_init to initialize internal data and channel_subsystem_init_sync to start scanning for devices and wait for it to finish. The start scanning for devices part is moved to the first initcall such that more work happens in parallel.
