Subject: [PATCH] scsi: sr: Fix some cdroms automatically ejected when booting into the system
Date: Wed, 27 Apr 2022 17:09:06 +0800 [thread overview]
Message-ID: <20220427090906.2257940-1-jinxiaobo@uniontech.com> (raw)
sr_get_events() has been called before udev starts when SCSI CDROM is
built-in and AHCI SATA is bulit-in,so sr events propagated to
user space are not handled.
if both is loadable, udev will handle sr events, some cdroms may eject.
We need call sr_get_events() once before device_add_disk()
to keep the same result, whether both are built-in or loadable.
