Setting acls on an xfs filesystem will succeed even after running out of space for user attributes. Use trusted attributes instead. Also speed up the test by setting large values for the attributes. [eguan: use perl to generate attr value, and add comments on trusted namespace] Signed-off-by: Ernesto A.

# Fill the device and set as many extended attributes to a file as
|
|
# possible. Then call setfacl on it and, if this fails for lack of
|
|
# space, test that the permissions remain the same.
