Use an ifdef in ext2_fs.h instead of a bogus separate file (ext2_fs_i.h)
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.
