* Fix major device check when locking partitionsCorinna Vinschen2016-06-241-10/+7
| | | | | | | | The change introduced in commit b2867a6 contains a faulty check for the major device number in fhandler_dev_floppy::lock_partition. Fix this. Also fix comments. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Handle up to 63 partitions per driveCorinna Vinschen2016-06-231-2/+3
| | | | | | | | | | | | | | Revamp device parsing code. Introducing support for more partitions into the shilka-generated parser has the unfortunate side-effect of raising the size of the DLL by almost 2 Megs. Therefore we split out the handling for /dev/sdXY devices into a tiny bit of hand-written code. While at it, remove some unused cruft from devices.* and generally clean up the device class to provide access methods instead of direct access to members.
