Subject: [PATCH] migrate: Wrap CONFIG_DEVICE_PRIVATE dependent function declarations with ifdef
Date: Wed, 9 Feb 2022 09:34:07 +0000 [thread overview]
Message-ID: <20220209093408.21780-1-sj@kernel.org> (raw)
'migrate_vma_{setup,pages,finalize}()' functions are defined under
CONFIG_DEVICE_PRIVATE, but their declarations are not. This commit
wraps the declaration under the config to minimize confusion.
