Messages in this thread Patch in this message | | | From | Tejun Heo <> | Subject | [PATCH 18/32] workqueue: use %*pb[l] to format bitmaps including cpumasks and nodemasks | Date | Sat, 24 Jan 2015 09:03:24 -0500 |
| |
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.
