The patch titled
Subject: rcu: use %*pb[l] to print bitmaps including cpumasks and nodemasks
has been removed from the -mm tree. Its filename was
rcu-use-%pb-to-print-bitmaps-including-cpumasks-and-nodemasks.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Tejun Heo <tj@xxxxxxxxxx>
Subject: rcu: 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()
