From a05c0205ba031c01bba33a21bf0a35920eb64833 Mon Sep 17 00:00:00 2001 From: "Martin K. Petersen" Date: Wed, 3 Jun 2009 09:33:18 +0200 Subject: block: Fix bounce limit setting in DM blk_queue_bounce_limit() is more than a wrapper about the request queue limits.bounce_pfn variable. Introduce blk_queue_bounce_pfn() which can be called by stacking drivers that wish to set the bounce limit explicitly. Signed-off-by: Martin K.
