Subject: scftorture: Avoid additional div operation.
X-Git-Tag: v6.13-rc1~200^2~4
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=42eeb3b5731de338a84a6d84e6318aeaa642a5b8;p=thirdparty%2Fkernel%2Fstable.git

scftorture: Avoid additional div operation.

Replace "scfp->cpu % nr_cpu_ids" with "cpu". This has been computed
earlier.
