Date: Sat, 24 Jan 2015 09:03:17 -0500 From: Tejun Heo <tj@...nel.org> To: akpm@...ux-foundation.org Cc: linux-kernel@...r.kernel.org, Tejun Heo <tj@...nel.org>, Chris Zankel <chris@...kel.net>, Max Filippov <jcmvbkbc@...il.com>, linux-xtensa@...ux-xtensa.org Subject: [PATCH 11/32] xtensa: use %*pb[l] to print bitmaps including cpumasks and nodemasks printk and friends can now formap 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 patch is dependent on the following two patches. lib/vsprintf: implement bitmap printing through '%*pb[l]' cpumask, nodemask: implement cpumask/nodemask_pr_args() Please wait till the forementioned patches are merged to mainline before applying to subsystem trees.
