From: Tejun Heo Date: Fri, 13 Feb 2015 22:37:34 +0000 (-0800) Subject: percpu: use %*pb[l] to print bitmaps including cpumasks and nodemasks X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=807de073bb5c92e6e19f2c3b7075b51e9d5f6a93;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git percpu: use %*pb[l] to print bitmaps including cpumasks and nodemasks printk and friends can now format bitmaps using '%*pb[l]'. cpumask and nodemask also provide cpumask_pr_args() and nodemask_pr_args() respectively which can be used to generate the two printf arguments necessary to format the specified cpu/nodemask.
