Hi,

Search for the thread from Andi Kleen on this list and my answer
https://www.redhat.com/archives/dm-devel/2010-July/msg00118.html

Mentioned patches are still not in Alasdair's tree but I have version
for (ongoing) review and for older kernels (with some small fixes I found)
here http://mbroz.fedorapeople.org/dm-crypt/

There is one problem with async crypto left but otherwise it is stable
(I am using it myself for weeks).

I hope it will reach 2.6.37 (with some other changes I want to do in dm-crypt).
(Also read the discussion I mentioned - it will not help in situation when only
one process generates all crypt IOs.)
