From d8dd7d768131010cb6e064036bf525db68ce78b8 Mon Sep 17 00:00:00 2001 From: Thomas Hellstrom Date: Tue, 3 Dec 2019 20:30:52 +0100 Subject: [PATCH] scsi: vmw_pvscsi: Silence dma mapping errors These errors typically occur with swiotlb when the swiotlb buffer is full. But they are transient and would typically unnecessarily worry a user. Instead of errors, print debug messages. Cc: "James E.J. Bottomley" Cc: "Martin K.
