So given the max attr name length is fixed by the kernel at 255 bytes (XATTR_NAME_MAX), that means the max value length is somewhere around 65000 bytes, not 1024 bytes? Really, we want to stress and exercise max supported sizes - if the admin reduces the max size on their test filesystems, that's not something we should be trying to work around in the test suite by preventing the test code from ever exercising attr values > 1024 bytes.....
