From 1b88b99bdff85e75df1cfaa418ed2ef8e1bffeb2 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 24 Jul 2019 08:52:56 +0200 Subject: nouveau: return -EBUSY when hmm_range_wait_until_valid fails -EAGAIN has a magic meaning for non-blocking faults, so don't overload it. Given that the caller doesn't check for specific error codes this change is purely cosmetic.
