From: Chris Smart Date: Sun, 3 Nov 2019 23:33:56 +0000 (+0000) Subject: powerpc/crypto: Add cond_resched() in crc-vpmsum self-test X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9f0acf9f80ad504573e6482fb00b53866a9b9d2f;p=linux.git 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.
