Subject: [PATCH] fix inode based symlink string length limit
Origin: http://genext2fs.cvs.sourceforge.net/viewvc/genext2fs/genext2fs/genext2fs.c?r1=1.95&r2=1.96
[ukl: I'm annoyed because this patch is more complicated than necessary.
Just doing s/>/>=/ in the 2nd line after the 2nd hunk has the same
effect as the 2nd hunk without code duplication and dead code]
