[PATCH 6/7] mm/gfp: make gfp_zonelist return directly and bool

Show all headers | View raw

This patch makes gfp_zonelist return bool due to this
particular function only using either one or zero as its return
value.

This patch also makes gfp_zonelist return directly by removing if.

No functional change.
