According to the man page, llseek its supossed to return 0 on successful
operation. It seems that e2fsck thinks that that is an error.

What version of libc are you using? I suspect what's going on is that
whoever implemented llseek in the libc did it differently than I had
anticipated. (See lib/ext2/llseek.c for how I expected it to be done;
yes, the llseek system call returns 0 for successful operation. I
however implemented the llseek functions so that it functions just like
lseek(); that is, it returns the **old** location of cursor on success,
instead of zero.)

A quick work around is to override configure such that you compile files
(epsecially lib/ext2fs/llseek.c), so that HAVE_LLSEEK is not this. This
will cause lib/ext2fs/llseek to use a built-in llseek() funct9ion, which
will work much better for llseek.c().
