From e4e1899aaec0370aea6b98597ee6289d60544ae2 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 17 Aug 2015 07:59:47 +0200 Subject: s390/zcrypt: use msleep() instead of mdelay() There is no need to busy loop and monopolize a cpu for up to ~2 seconds. The code in question that calls mdelay() is preemptible anyway, so better let the kernel schedule different processes than just looping and causing unnecessary delays.
