From 97750cebb3000a9cc08f8ce8dc8c7143be7d7201 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 6 Sep 2010 17:56:29 +0200 Subject: libata: add @ap to ata_wait_register() and introduce ata_msleep() Add optional @ap argument to ata_wait_register() and replace msleep() calls with ata_msleep() which take optional @ap in addition to the duration. These will be used to implement EH exclusion. This patch doesn't cause any behavior difference.
