Thanks for the fix!

Steve can you put that an top of ksmbd-for-next for the moment.
Then I'll squash the hunks in the correct patch and provide
a new branch, as the 2nd would have:

Fixes: 30807ad55601 ("smb: server: make use of smbdirect.ko")

But both hashes are unlikely be the ones landing upstream,
so as we do rebase anyway I'd squash them, but maybe
I'll have time for the rebase after -rc4.

So we should take it as is for now, but maybe without the
Fixes tag, but acked by me.

Thanks!
