From: Namhyung Kim on 10 Aug 2010 22:20 When pcpu_build_alloc_info() searches best_upa value, it ignores current value if the number of waste units exceeds 1/3 of the number of total cpus. But the comment on the code says that it will ignore if wastage is over 25%. Modify the comment. Signed-off-by: Namhyung Kim <namhyung(a)gmail.com> --- I used -U5 rather than 3 for you to see the mismatch at a glance. :-) mm/percpu.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/mm/percpu.c b/mm/percpu.c index 9581f84..5e78131 100644 --- a/mm/percpu.c +++ b/mm/percpu.c @@ -1174,11 +1174,11 @@ struct pcpu_alloc_info * __init pcpu_build_alloc_info( allocs += this_allocs; wasted += this_allocs * upa - group_cnt[group]; } /* - * Don't accept if wastage is over 25%.
