[PATCH 0/7] some small improvement

[Yaowei Bai <baiyaowei@cmss.chinamobile.com>]

This patchset only performs some small improvement to mm. First, make
several functions return bool to improve readability, and then remove
unused is_unevictable_lru function and refactor memmap_valid_within
for simplicity.

No functional change.

Yaowei Bai (7):
  ipc/shm: is_file_shm_hugepages can be boolean
  mm/hugetlb: is_file_hugepages can be boolean
  mm/memblock: memblock_is_memory/reserved can be boolean
  mm/vmscan: page_is_file_cache can be boolean
  mm/lru: remove unused is_unevictable_lru function
  mm/gfp: make gfp_zonelist return directly and bool
  mm/mmzone: refactor memmap_valid_within
