[PATCH 00/19] smbdirect client/server credit fixes

[Stefan Metzmacher <metze@samba.org>]

Hi,

here is my current state of the regression
fixes we have in 6.18 and 6.19-rc6.

The generic and server patches were tested
in as is, but without this 07/19
smb: server: let send_done handle a completionwithout IB_SEND_SIGNALED,
but the related logic was tested on my branch with common code.

The client patches are not tested yet,
but they compile and I want to make it possible
to include in linux-next for testing.

I also need to add some more Fixes tags.

I'll do more tests with this tomorrow.
