From da4ad3a23af3d7f357b24b33e9fec7531b59ee49 Mon Sep 17 00:00:00 2001 From: Mike Snitzer Date: Mon, 22 Oct 2018 10:59:52 -0400 Subject: [PATCH] dm writecache: remove disabled code in memory_entry() This dead branch was missed during review. It only makes memory_entry() more inefficient due to needless call to is_power_of_2(), etc. Reported-by: shenghui Signed-off-by: Mike Snitzer --- drivers/md/dm-writecache.c | 5 +---- 1 file changed, 1 insertion(+), 4 deletions(-) diff --git a/drivers/md/dm-writecache.c b/drivers/md/dm-writecache.c index 5f1f80d424dd..2d50eec94cd7 100644 --- a/drivers/md/dm-writecache.c +++ b/drivers/md/dm-writecache.c @@ -350,10 +350,7 @@ static struct wc_memory_superblock *sb(struct dm_writecache *wc) static struct wc_memory_entry *memory_entry(struct dm_writecache *wc, struct wc_entry *e) { - if (is_power_of_2(sizeof(struct wc_entry)) && 0) - return &sb(wc)->entries[e - wc->entries]; - else - return &sb(wc)->entries[e->index]; + return &sb(wc)->entries[e->index]; } static void *memory_data(struct dm_writecache *wc, struct wc_entry *e)
