limit minixfs printks on corrupted dir i_size (CVE-2006-6058)
First reported at http://projects.info-pull.com/mokb/MOKB-17-11-2006.html
Essentially a corrupted minix dir inode reporting a very large
i_size will loop for a very long time in minix_readdir, minix_find_entry,
etc, because on EIO they just move on to try the next page. This is
under the BKL, printk-storming as well. This can lock up the machine
for a very long time. Simply ratelimiting the printks gets things back
under control. Make the message a bit more informative while we're here.
Adrian Bunk:
Backported to 2.6.16.
