[Qemu-devel] [PATCH 0/3] scsi: eject fixed

[Alexey Kardashevskiy <aik@ozlabs.ru>]

The initial problem was if the user ejects a ISO/DVD mounted in Fedora19,
the block device went into weird state when QEMU's monitor reported that
it is locked, has medium but tray open (some debug output is below).

Please comment. Thanks!
