Subject: [PATCH v2] mm: zsmalloc: Replace return type int with bool
Date: Tue, 20 Feb 2018 23:28:11 +0530 [thread overview]
Message-ID: <20180220175811.GA28277@jordon-HP-15-Notebook-PC> (raw)
zs_register_migration() returns either 0 or 1.
So the return type int should be replaced with bool.

v2: Returning false in zs_register_migration() as return
type is bool
