From: Zhouyi Zhou <zhouzhouyi@gmail.com>
currently tools/testing/selftests/rcutorture/bin/torture.sh reports false positve because of kthread printing.
Commit "printk: add functions to prefer direct printing" (2bb2b7b57f812) have added functions to prefer direct printing activated for the primary import messages.
Meanwhile adding printk_prefer_direct_enter/exit to torture_cleanup_begin/end still can't eliminate the false positives for a hundred percent.
This patch add pr_flush to torture_cleanup_end because the latter is sleepable.
