Subject: BTRFS, encrypted LVM and disk write cache ?

Hi list,
I'm a new BTRFS user and will try not to ask FAQs ;-)
I'm currently using Btrfs v0.19 on stock Ubuntu Natty (kernel 2.6.38)
and use a BTRFS inside an encrypted LVM.
The wiki "gotchas" page https://btrfs.wiki.kernel.org/index.php/Gotchas
states :
=C2=AB btrfs volumes on top of dm-crypt block devices (and possibly LVM=
)
require write-caching to be turned off on the underlying HDD. Failing t=
o
do so, in the event of a power failure, may result in corruption not ye=
t
handled by btrfs code. (2.6.33) =C2=BB
=2E..So I've turned my write cache off, but I notice this is stated for
kernel 2.6.33, so wonder if this still is an issue with 2.6.38, or has
it been addressed since ?
Thanks in advance for your help.
Kind regards.
