Confirmed: it works! Thanks very much!
BTW, when using this cifs mounted directory I need to use:
export GODEBUG=asyncpreemptoff=1
As seen in Seeing "failed to read directory entry: readdirent: no such file or directory" with v1.52.2 - #24 by Meliox . If you wanted me to test anything for this let me know. I didn't test the old builds from that thread. With the asyncpreemptoff all is good.
