From 9f0acf9f80ad504573e6482fb00b53866a9b9d2f Mon Sep 17 00:00:00 2001 From: Chris Smart Date: Sun, 3 Nov 2019 23:33:56 +0000 Subject: [PATCH] powerpc/crypto: Add cond_resched() in crc-vpmsum self-test The stress test for vpmsum implementations executes a long for loop in the kernel. This blocks the scheduler, which prevents other tasks from running, resulting in a warning. This fix adds a call to cond_reshed() at the end of each loop, which allows the scheduler to run other tasks as required.
