I think we need both because the CONFIG_CHECKPOINT_RESTORE macro was not 
introduced since 3.8. Before 3.8, we can enable this config but the 
kernel does not support this MSG_COPY FLAG.
also using "CONFIG_CHECKPOINT_RESTORE=y" is better.

Agree. xfstests often does this(removing the useless case and new case 
uses this test name).
