[OpenIndiana-discuss] linux disk filter

[Michael Schuster]

Hi,

erm. This list is dedicated to OpenIndiana, which is NOT a flavour of
linux. While userland may look similar in many aspects, the kernel most
definitely does not, so even if you may get lucky and "find" someone who
can help you, I'd suggest you look for a linux-oriented mailing list and
ask there - I don't know much about linux, I'd start looking at kernel.org,
maybe there's some pointers there.

good luck
Michael
