A built-in SMB file system cannot link against a modular
infiniband core module:
fs/cifs/smbdirect.o: In function `smbd_destroy_rdma_work':

This changes the Kconfig dependency to enforce selecting one of the
valid configurations.

Is this really correct? Should CIFS_SMB_DIRECT be allowed with:
CIFS=n and INFINIBAND=y ???
or
CIFS=m and INFINIBAND=n ???
I guess a more complex logic should be used here
or am I missing something?

The two ones you listed are prohibited by the existing
'depends on CIFS && INFINIBAND' dependency.
We could rephrase the dependency as
depends on (CIFS=y && INFINIBAND=y) || \
(CIFS=m && INFINIBAND=y) || \
(CIFS=m && INFINIBAND=m)
which has the same effect as
depends on CIFS && INFINIBAND
depends on CIFS=m || INFINIBAND=y
but I don't think that adds any clarity.

Thanks for the clarification!
I somehow assumed the patch has been:
- depends on CIFS && INFINIBAND
+ depends on CIFS=m || INFINIBAND=y
instead of:
depends on CIFS && INFINIBAND
+ depends on CIFS=m || INFINIBAND=y

How about we change them to
depends on CIFS=m && INFINIBAND || CIFS=y && INFINIBAND=y

Yes, that seems fine. I would normally group them using () to avoid
any confusion with operator precedence, but your version is
