Hmm.  The failure case in file.c is the module tries to seek past the
EOF.  In that case, since the stream is open read only the lseek returns
EINVAL.  The location of the file pointer is left at it's previous
position, and p_access->info.i_pos says it is past the EOF location. 
I'm surprised this doesn't cause really bad things to happen...

BTW.  It just occurred to me.  Shouldn't file.c be using lseek64, not lseek?
