From a732c207d19e899845ae47139708af898daaf9fd Mon Sep 17 00:00:00 2001 From: Mike Snitzer Date: Thu, 23 Jul 2009 20:30:40 +0100 Subject: dm: remove queue next_ordered workaround for barriers This patch removes DM's bio-based vs request-based conditional setting of next_ordered. For bio-based DM the next_ordered check is no longer a concern (as that check is now in the __make_request path). For request-based DM the default of QUEUE_ORDERED_NONE is now appropriate. bio-based DM was changed to work-around the previously misplaced next_ordered check with this commit: 99360b4c18f7675b50d283301d46d755affe75fd request-based DM does not yet support barriers but reacted to the above bio-based DM change with this commit: 5d67aa2366ccb8257d103d0b43df855605c3c086 The above changes are no longer needed given Neil Brown's recent fix to put the next_ordered check in the __make_request path: db64f680ba4b5c56c4be59f0698000df89ff0281 Signed-off-by: Mike Snitzer Cc: Jun'ichi Nomura Cc: NeilBrown Acked-by: Kiyoshi Ueda Acked-by: Mikulas Patocka Signed-off-by: Alasdair G Kergon --- drivers/md/dm.h | 1 - 1 file changed, 1 deletion(-) (limited to 'drivers/md/dm.h') diff --git a/drivers/md/dm.h b/drivers/md/dm.h index 23278ae..a7663eb 100644 --- a/drivers/md/dm.h +++ b/drivers/md/dm.h @@ -61,7 +61,6 @@ int dm_table_any_congested(struct dm_table *t, int bdi_bits); int dm_table_any_busy_target(struct dm_table *t); int dm_table_set_type(struct dm_table *t); unsigned dm_table_get_type(struct dm_table *t); -bool dm_table_bio_based(struct dm_table *t); bool dm_table_request_based(struct dm_table *t); int dm_table_alloc_md_mempools(struct dm_table *t); void dm_table_free_md_mempools(struct dm_table *t); -- cgit v1.1
