From 2351f431f727223b4d82851ee8fc045bf51edd34 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Wed, 27 Sep 2017 10:43:13 -0400 Subject: btrfs: fix send ioctl on 32bit with 64bit kernel We pass in a pointer in our send arg struct, this means the struct size doesn't match with 32bit user space and 64bit kernel space. Fix this by adding a compat mode and doing the appropriate conversion.
