and refuse initializing filesystems with a wrong version. This will aid maintenance activites on the 5-stable branch. s/vfs_mount/vfs_omount/ s/vfs_nmount/vfs_mount/ Name our filesystems mount function consistently. Eliminate the namiedata argument to both vfs_mount and vfs_omount. It was originally there to save stack space. A few places abused it to get hold of some credentials to pass around. Effectively it is unused. Reorganize the root filesystem selection code.
