Remove custom code to pack/unpack dev_t's. Under Linux all dev_t's are an unsigned 32-bit value even on 64-bit platforms. The lower 20 bits are used for the minor number and the upper 12 for the major number. This means if your importing a pool from Solaris you may get strange major/minor numbers. But it doesn't really matter because even if we add compatibility code to translate the encoded Solaris major/minor they won't do you any good under Linux. You will still need to recreate the dev_t with a major/minor which maps to reserved major numbers used under Linux. Dropping this code also resolves 32-bit builds by removing the offending 32-bit compatibility code.
Native ZFS for Linux! ZFS is an advanced file system and volume manager which was originally developed for Solaris. It has been successfully ported to FreeBSD and now there is a functional Linux ZFS kernel port too. The port currently includes a fully functional and stable SPA, DMU, and ZVOL with a ZFS Posix Layer (ZPL) on the way!
