From 93aae17af1172c40c6f74b7294e93a90c3cfaa5d Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Thu, 16 Dec 2010 17:52:17 +0100 Subject: sr: implement sr_check_events() Replace sr_media_change() with sr_check_events(). It normally only uses GET_EVENT_STATUS_NOTIFICATION to check both media change and eject request. If @clearing includes DISK_EVENT_MEDIA_CHANGE, it issues TUR and compares whether media presence has changed. The SCSI specific media change uevent is kept for compatibility. sr_media_change() was doing both media change check and revalidation. The revalidation part is split into sr_block_revalidate_disk().
