hi, i`m sorry, I made some mistakes in last email. I have been studying mm and learn age_activate_anon(), at the very beginning I felt confuse when I saw activate_page_pvecs, after I learned the whole thing I understood that it's similar with other pagevec's function. Can we put it with other pagevec together? I think it is easier for newbies to read and understand. regards, Signed-off-by: Ming Li <mingli199x@xxxxxx> --- mm/swap.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/mm/swap.c b/mm/swap.c index 09fe5e9..5c9901c 100644 --- a/mm/swap.c +++ b/mm/swap.c @@ -47,6 +47,9 @@ static DEFINE_PER_CPU(struct pagevec, lru_add_pvec); static DEFINE_PER_CPU(struct pagevec, lru_rotate_pvecs); static DEFINE_PER_CPU(struct pagevec, lru_deactivate_file_pvecs); static DEFINE_PER_CPU(struct pagevec, lru_deactivate_pvecs); +#ifdef CONFIG_SMP +static DEFINE_PER_CPU(struct pagevec, activate_page_pvecs); +#endif /* * This path almost never happens for VM activity - pages are normally @@ -274,8 +277,6 @@ static void __activate_page(struct page *page, struct lruvec *lruvec, } #ifdef CONFIG_SMP -static DEFINE_PER_CPU(struct pagevec, activate_page_pvecs); - static void activate_page_drain(int cpu) { struct pagevec *pvec = &per_cpu(activate_page_pvecs, cpu); -- 1.8.3.1ÿôèº{.nÇ+?·ÿ±éÝjg¬±¨Â+aþéì¹»®&Þ?)îÇù¦þ)í?æèw+h?¨èÚ&£ù/iÉÿ¢¸ÿ?梷¢?ú(?¸§»þÇ?þm§ÿÿÃÿ?)îÇù¦þ?àÿðè?û^?¨¥ÿö¡ç?¨¥¶?ÿv?íþKÚrOè®ÿzf¢?ù/iÉÿ¢¸ÿ
