/* This file contains the legacy sync interface used by Android platform and
* device code. The direct contents will be removed over time as code
* transitions to using the updated interface in ndk/sync.h. When this file is
* empty other than the ndk/sync.h include, that file will be renamed to
* replace this one.
* New code should continue to include this file (#include <android/sync.h>)
* instead of ndk/sync.h so the eventual rename is seamless, but should only
* use the things declared in ndk/sync.h.
* This file used to be called sync/sync.h, but we renamed to that both the
* platform and NDK call it android/sync.h. A symlink from the old name to this
* one exists temporarily to avoid having to change all sync clients
* simultaneously. It will be removed when they've been updated, and probably
* after this change has been delivered to AOSP so that integrations don't
* break builds.
