From: Tejun Heo Date: Fri, 13 Feb 2015 22:37:37 +0000 (-0800) Subject: workqueue: use %*pb[l] to format bitmaps including cpumasks and nodemasks X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dfbcbf42dd07b649bb02b1558e2c7150c035b4dc;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git workqueue: use %*pb[l] to format 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.
