Tom, and Ralph.
Some background on the cifsd directory name:

We discussed in length but we decided with cifsd to align with the
current directory name cifs for the client.
Just to align with current praxis defined by other filesystems, i.e.
nfs. which has nfs for client, nfsd for server
and nfs_common for shared cod and definitions.

Once cifsd lands in the kernel I expect we will start building
cifs_common for this purpose.

An alternative would have been to rename the current fs/cifs tree to
fs/ksmb but renaming an entire directory tree
felt it might get pushback.
In the end we thought that the module name, that is user visible and
there it is important we call it smb3 something
but the source tree is not end-user visible so it was less important
what the name was.

(the alternative ending up with fs/cifs fs/ksmbd and fs/cifs_common
would have been terrible)
