Attempting to perform a vfs_rename() on Linux 4.2 and newer kernels results in an EACCES error. Rather than attempting to add and maintain more ugly compatibility code it's best to just retire this interface. As a first step the SPLAT test is disabled for Linux 4.2 and newer kernels. vn_rename: Failed vn_rename /tmp/vn.tmp.1 -> /tmp/vn.tmp.2 (13) Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Issue zfsonlinux/zfs#3653
