From 2985259b0e3928d4cd0723ac5aad0d1190ab7717 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Tue, 19 Dec 2006 08:27:31 +0100 Subject: [PATCH] [PATCH] ->nr_sectors and ->hard_nr_sectors are not used for BLOCK_PC requests It's a file system thing, for block requests the only size used in the io paths is ->data_len as it is in bytes, not sectors.
