support is partial in that it will refuse to create large files on
filesystems that haven't been upgraded to EXT2_DYN_REV or that don't
have the EXT2_FEATURE_RO_COMPAT_LARGE_FILE flag set in the superblock.

shared code and converting all ufs references. Originally it may
have made sense to share common features between the two filesystems,
but recently it has only caused problems, the UFS2 work being the
final straw.
All UFS_* indirect calls are now direct calls to ext2_* functions,
and ext2fs-specific mount and inode structures have been introduced.
main changes are:
- many things are more dynamic; e.g., the inode size is a new parameter
in the superblock instead of a constant.
- extensions are controlled by new flags in the superblock.
- directory entries may have a file type field.
These changes are not used yet, except for a spelling change which affects
ext2_cnv.c
to avoid the namespace problems caused by <ufs/ufs/inode.h> #defining
i_mode, etc.
ext2_fs_i.h had nothing to do with the Linux version. It was a small
part of the Linux version of ext2_fs.h (the part that declares extra
in-core fields for an inode). We don't need it because we use the
ufs in-core inode for the extra fields.
changes, so don't expect to be able to run the kernel as-is (very well)
without the appropriate Lite/2 userland changes.
The system boots and can mount UFS filesystems.
Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
Mount_std mounts will not work until the getfsent
library routine is changed.

Included <sys/vnode.h> and its prerequisite <sys/proc.h>, and cleaned
up includes. The vop_t changes made the non-inclusion of vnode.h
fatal instead of just sloppy.
i386_bitops.h:
Changed `extern inline' to `static inline'. `extern inline' is a
Linuxism that stops things from compiling without -O. Fixed
idempotency identifier.
Misc:
Added prototypes. Staticized some functions so that prototypes are
unnecessary. Added casts. Cleaned up includes.
file for GPL restrictions. This code was ported to the BSD platform
by Godmar Back <gback@facility.cs.utah.edu> and specifically to FreeBSD
by John Dyson. This code is still green and should be used with caution.
Additional changes to UFS necessary to make this code work will be commited
seperately.
