Subject: mm/memblock.c: memblock_is_memory()/reserved() can be boolean
X-Git-Tag: v4.5-rc1~94^2~74
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=b4ad0c7e004a2cc0e52790eff72f5176b59ca386;p=users%2Fjedix%2Flinux-maple.git

mm/memblock.c: memblock_is_memory()/reserved() can be boolean

Make memblock_is_memory() and memblock_is_reserved return bool to
improve readability due to these particular functions only using either
one or zero as their return value.

No functional change.
