"ESSIV was designed by Clemens Fruhwirth and has been integrated into  
the Linux kernel since version 2.6.10"
   -- http://en.wikipedia.org/wiki/Disk_encryption_theory

Thus according to Wikipedia's version of history, the watermarking  
attack has been addressed since 2.6.10 regardless of other disk- 
specific encryption modes. Clemens appears to be responsible for http://clemens.endorphin.org/publications 
, which lists ESSIV as being part of Linux 2.6.10.

My research consisted of a few seconds of quality time with Google. Do  
not use this information to run nuclear power plants, yadda yadda.
