Thanks for testing it.

Steve, I would suggest below commits for v6.5.y

	238b351d0935 ("smb3: allow controlling length of time directory entries are cached with dir leases")
	6a50d71d0fff ("smb3: allow controlling maximum number of cached directories")
	2da338ff752a ("smb3: do not start laundromat thread when dir leases  disabled")
	e95f3f744650 ("smb: client: make laundromat a delayed worker")
	81ba10959970 ("smb: client: prevent new fids from being removed by laundromat")

If OK, please ask stable team to pick those up.
