Its filename is percpu-use-%pb-to-print-bitmaps-including-cpumasks-and-nodemasks.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/percpu-use-%25pb-to-print-bitmaps-including-cpumasks-and-nodemasks.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/percpu-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: percpu: 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 Cc: Christoph Lameter Signed-off-by: Andrew Morton --- mm/percpu.c | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) diff -puN mm/percpu.c~percpu-use-%pb-to-print-bitmaps-including-cpumasks-and-nodemasks mm/percpu.c --- a/mm/percpu.c~percpu-use-%pb-to-print-bitmaps-including-cpumasks-and-nodemasks +++ a/mm/percpu.c @@ -1528,7 +1528,6 @@ static void pcpu_dump_alloc_info(const c int __init pcpu_setup_first_chunk(const struct pcpu_alloc_info *ai, void *base_addr) { - static char cpus_buf[4096] __initdata;
