------------------------------------------------------
From: Yaowei Bai <baiyaowei@xxxxxxxxxxxxxxxxxxxx>
Subject: ipc/shm.c: is_file_shm_hugepages() can be boolean
Make is_file_shm_hugepages() return bool to improve readability due to
this particular function only using either one or zero as its return
value.
No functional change.
