From 5024c1d71b988ca5da94e52461626e9930015681 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 13 Feb 2015 14:37:59 -0800 Subject: slub: 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. * This is an equivalent conversion but the whole function should be converted to use scnprinf famiily of functions rather than performing custom output length predictions in multiple places.
