Use udev to create /dev/zvol/[dataset_name] links This commit allows zvols with names longer than 32 characters, which fixes issue on https://github.com/behlendorf/zfs/issues/#issue/102. Changes include: - use /dev/zd* device names for zvol, where * is the device minor (include/sys/fs/zfs.h, module/zfs/zvol.c). - add BLKZNAME ioctl to get dataset name from userland (include/sys/fs/zfs.h, module/zfs/zvol.c, cmd/zvol_id). - add udev rule to create /dev/zvol/[dataset_name] and the legacy /dev/[dataset_name] symlink. For partitions on zvol, it will create /dev/zvol/[dataset_name]-part* (etc/udev/rules.d/60-zvol.rules, cmd/zvol_id).
