I am using kernel 2.2.14 with patch-int-2.2.13.3. I have a blowfish
encrypted filesystem with this in etc/fstab:

/dev/hdb2 /home/svmcguir/CRYPT ext2 defaults,noauto,loop,encryption=blowfish,user 0 0

I mounted and used then umounted the filesystem. It really is gone:

[root@homebox /root]# mount
/dev/hda2 on / type ext2 (rw)
none on /proc type proc (rw)
/dev/hda3 on /usr/local type ext2 (rw,sync)
/dev/hdb1 on /home type ext2 (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)

but I can still read a file that was there:

I think this is bad. Can this be the result of using kernel 2.2.14
with the patch for 2.2.13?
