33# DESCRIPTION:
34# The zfs_xattr_compat tunable and fallback works as expected.
35#
36# STRATEGY:
37#	For both of xattr=sa and xattr=dir:
38#	1. Create a filesystem with the native zfs_xattr_compat
39#	2. Create a file on the filesystem and add some xattrs to it
40#	3. Change the zfs_xattr_compat to the alternative setting
41#	4. Verify that the xattrs can still be accessed and modified
42#	5. Change zfs_xattr_compat back to the native setting
43#	6. Verify that the xattrs can still be accessed and modified
44#
