Its filename is proc-use-%pb-to-print-bitmaps-including-cpumasks-and-nodemasks.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/proc-use-%25pb-to-print-bitmaps-including-cpumasks-and-nodemasks.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/proc-use-%25pb-to-print-bitmaps-including-cpumasks-and-nodemasks.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/SubmitChecklist when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Tejun Heo Subject: proc: 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() Signed-off-by: Tejun Heo Signed-off-by: Andrew Morton --- fs/proc/array.c | 10 ++++------ 1 file changed, 4 insertions(+), 6 deletions(-) diff -puN fs/proc/array.c~proc-use-%pb-to-print-bitmaps-including-cpumasks-and-nodemasks fs/proc/array.c --- a/fs/proc/array.c~proc-use-%pb-to-print-bitmaps-including-cpumasks-and-nodemasks +++ a/fs/proc/array.c @@ -316,12 +316,10 @@ static inline void task_context_switch_c static void task_cpus_allowed(struct seq_file *m, struct task_struct *task) { - seq_puts(m, "Cpus_allowed:\t");
