From 8fc04e6ea02d631fd344f462002078b8067793de Mon Sep 17 00:00:00 2001 From: Ming Lei Date: Tue, 28 Mar 2017 16:17:55 +0800 Subject: md: raid1: kill warning on powerpc_pseries This patch kills the warning reported on powerpc_pseries, and actually we don't need the initialization. After merging the md tree, today's linux-next build (powerpc pseries_le_defconfig) produced this warning: drivers/md/raid1.c: In function 'raid1d': drivers/md/raid1.c:2172:9: warning: 'page_len$' may be used uninitialized in this function [-Wmaybe-uninitialized] if (memcmp(page_address(ppages[j]), ^ drivers/md/raid1.c:2160:7: note: 'page_len$' was declared here int page_len[RESYNC_PAGES]; ^ Signed-off-by: Ming Lei Signed-off-by: Shaohua Li --- drivers/md/raid1.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/md/raid1.c') diff --git a/drivers/md/raid1.c b/drivers/md/raid1.c index b7d9651286d4..7d6723558fd8 100644 --- a/drivers/md/raid1.c +++ b/drivers/md/raid1.c @@ -2157,7 +2157,7 @@ static void process_checks(struct r1bio *r1_bio) struct page **ppages = get_resync_pages(pbio)->pages; struct page **spages = get_resync_pages(sbio)->pages; struct bio_vec *bi; - int page_len[RESYNC_PAGES]; + int page_len[RESYNC_PAGES] = { 0 }; if (sbio->bi_end_io != end_sync_read) continue; -- cgit v1.2.3
