34# DESCRIPTION:
35# The noxattr mount option functions as expected
36#
37# STRATEGY:
38#	1. Create a file on a filesystem and add an xattr to it
39#	2. Unmount the filesystem, and mount it -o noxattr
40#	3. Verify that the xattr cannot be read and new files
41#	   cannot have xattrs set on them.
42#	4. Unmount and mount the filesystem normally
43#	5. Verify that xattrs can be set and accessed again
44#
