[PATCH 00/18] smb: smbdirect: more use of common structures e.g. smbdirect_send_io

[Stefan Metzmacher <metze@samba.org>]

Hi,

this is the next step towards a common smbdirect layer
between cifs.ko and ksmbd.ko, with the aim to provide
a socket layer for userspace usage at the end of the road.

This patchset focuses on the usage of a common
smbdirect_send_io and related structures in smbdirect_socket.send_io.

Note only patches 01-08 are intended to be merged soon,
while the ksmbd patches 09-18 are only posted for
completeness (as discussed with Namjae) to get early feedback.

I used the following xfstests as regression tests:
cifs/001 generic/001 generic/002 generic/005 generic/006 generic/007 generic/010 generic/011

Between cifs.ko against ksmbd.ko via siw.ko in all combinations
with and without the patchset on each side.
