Re: loop-AES and XFS corruption

[Paul Norris <pauln@physics.ucf.edu>]

I have used loop-AES on my laptop for over 6 months with no problems.
While you can't exactly call a 4200 rpm HDD high I/O, it's just another
users experience.  I have used it with kernel 2.4.14-18 now and have never
had problem one.
