From 10c0b3437c4dc0d14ac254bbe71e54ea5f238d97 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Fri, 1 May 2009 20:29:53 +0200 Subject: ide-tape: fix potential fs requests bug ide-tape had a potential bug for fs requests when preparing the command packet: it was writing the transfer length as a number of fixed blocks. However, the block layer implies 512 byte blocks and ide-tape can have other block sizes so account for that too. ide-floppy does this calculation properly with the block size factor (floppy->bs_factor).
