From: Gerald Schaefer Date: Wed, 10 Mar 2021 13:23:37 +0000 (+0100) Subject: s390/vtime: fix increased steal time accounting X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d54cb7d54877d529bc1e0e1f47a3dd082f73add3;p=linux.git s390/vtime: fix increased steal time accounting Commit 152e9b8676c6e ("s390/vtime: steal time exponential moving average") inadvertently changed the input value for account_steal_time() from "cputime_to_nsecs(steal)" to just "steal", resulting in broken increased steal time accounting. Fix this by changing it back to "cputime_to_nsecs(steal)".
