From 5b03a1b140e13a28ff6be1526892a9dc538ddef6 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 9 Mar 2011 19:54:27 +0100 Subject: ide: Convert to bdops->check_events() Convert ->media_changed() to the new ->check_events() method. The conversion is mostly mechanical. The only notable change is that cdrom now doesn't generate any event if @slot_nr isn't CDSL_CURRENT. It used to return -EINVAL which would be treated as media changed. As media changer isn't supported anyway, this doesn't make any difference. This makes ide emit the standard disk events and allows kernel event polling. Currently, only MEDIA_CHANGE event is implemented. Adding support for EJECT_REQUEST shouldn't be difficult; however, given that ide driver is already deprecated, it probably is best to leave it alone.
