From 5a7bbad27a410350e64a2d7f5ec18fc73836c14f Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 12 Sep 2011 12:12:01 +0200 Subject: block: remove support for bio remapping from ->make_request There is very little benefit in allowing to let a ->make_request instance update the bios device and sector and loop around it in __generic_make_request when we can archive the same through calling generic_make_request from the driver and letting the loop in generic_make_request handle it. Note that various drivers got the return value from ->make_request and returned non-zero values for errors.
