From 8680441caa5465a2cd87b6be857be4378df46700 Mon Sep 17 00:00:00 2001 From: Namjae Jeon Date: Thu, 25 Apr 2013 11:45:21 +0900 Subject: [PATCH] f2fs: add REQ_META about metadata requests for submit Adding REQ_META for all the metadata requests can help in improving the FS performance, if the underlying device supports TAGGING. So, when considering the submit_bio path for all the f2fs requests. We can add REQ_META for all the META requests. As a precursor to this change we considered the commit 4265900e0be653f5b78baf2816857ef57cf1332f 'mmc: MMC-4.5 Data Tag Support' Signed-off-by: Namjae Jeon Signed-off-by: Amit Sahrawat Signed-off-by: Jaegeuk Kim --- fs/f2fs/segment.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/fs/f2fs/segment.c b/fs/f2fs/segment.c index 0a652848a9f8..392ccb3d10b9 100644 --- a/fs/f2fs/segment.c +++ b/fs/f2fs/segment.c @@ -688,6 +688,9 @@ static void do_submit_bio(struct f2fs_sb_info *sbi, if (type >= META_FLUSH) rw = WRITE_FLUSH_FUA; + if (btype == META) + rw |= REQ_META; + if (sbi->bio[btype]) { struct bio_private *p = sbi->bio[btype]->bi_private; p->sbi = sbi;
