From 7a865e8ac3a8ead776ea2c8c74fa2b2d00a2c9cf Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 2 Dec 2008 09:52:24 -0500 Subject: [PATCH] Btrfs: btrfs: pass void __user * to btrfs_ioctl_clone_range Cleans the code up a little and also avoids a sparse warning due to the incorrect cast in the current version of the code.
