For legacy reasons the zvol.c and vdev_disk.c Linux compatibility code ended up in sys/blkdev.h and sys/vdev_disk.h headers. While there are worse places for this code to live it should be in a linux/blkdev_compat.h header. This change moves this block device Linux compatibility code in to the linux/blkdev_compat.h header and updates all the correct #include locations. This is not a functional change or bug fix, it is just code cleanup.
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!
$ ./configure
$ make pkg
