Long, long, long ago when the effort to port ZFS was begun the zfs_create_fs() function was heavily modified to remove all of its VFS dependencies. This allowed Lustre to use the dataset without us having to spend the time porting all the required VFS code. Fast-forward several years and we now have all the VFS code in place but are still relying on the modified zfs_create_fs(). This isn't required anymore and we can now use zfs_mknode() to create the root znode for the filesystem. This commit reverts the contents of zfs_create_fs() to largely match the upstream OpenSolaris code. There have been minor modifications to accomidate the Linux VFS but that is all. This code fixes issue #116 by bootstraping enough of the VFS data structures so we can rely on zfs_mknode() to create the root directory. This ensures it is created properly with support for system attributes. Previously it wasn't which is why it behaved differently that all other directories when modified.

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!
