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