Given that I can traverse the mount table and obtain the struct fs via the
superblock, and that I know the inode number, how do I read an inode from 
the filesystem?

I assumed from <ufs/fs.h> that I should say:

	blk = itod(fs, inum);
	off = itoo(fs, inum);

	seekpos = blk * fs->fs_bsize + off * sizeof(struct inode);

and then lseek to seekpos on the filesystem device and read sizeof(struct inode)
bytes.

(BTW, I assumed I had to multiply off by sizeof(struct inode) since with
two files with inodes x and x+1, the value I get for blk is constant and the
value for off is either y or y+1, respectively).

However I'm just getting garbage back on the read. I tried the fsbtodb macro 
in <ufs/fs.h> will no improvement.

What's the simple way to read a given inode given the appropriate struct fs
and the inode number? Alternatively, what's wrong with any of my assumptions
above?

Thanks in advance...
