Subject: [PATCH -next RFC 03/11] cpuset: change return type of is_partition_[in]valid to bool

From: Chen Ridong <chenridong@...wei.com>

The functions is_partition_valid() and is_partition_invalid() logically
return boolean values, but were previously declared with return type
'int'. This patch changes their return type to 'bool' to better reflect
their semantic meaning and improve type safety.
