From 7616c0ad2087c7d244b8985390c63059a6223c45 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Fri, 18 Apr 2008 00:46:26 +0200 Subject: ide: add ide_atapi_{discard_data,write_zeros} inline helpers Add ide_atapi_{discard_data,write_zeros} inline helpers to and use them instead of home-brewn helpers in ide-{floppy,tape,scsi}. There should be no functional changes caused by this patch.
