From 85c95f208f481ab3c34c4622f508272cd4803afd Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Mon, 10 Sep 2018 16:21:18 -0700 Subject: vfs: dedupe should return EPERM if permission is not granted Right now we return EINVAL if a process does not have permission to dedupe a file. This was an oversight on my part. EPERM gives a true description of the nature of our error, and EINVAL is already used for the case that the filesystem does not support dedupe.
