  22 /* This file contains the legacy sync interface used by Android platform and
  23  * device code. The direct contents will be removed over time as code
  24  * transitions to using the updated interface in ndk/sync.h. When this file is
  25  * empty other than the ndk/sync.h include, that file will be renamed to
  26  * replace this one.
  27  *
  28  * New code should continue to include this file (#include <android/sync.h>)
  29  * instead of ndk/sync.h so the eventual rename is seamless, but should only
  30  * use the things declared in ndk/sync.h.
  31  *
  32  * This file used to be called sync/sync.h, but we renamed to that both the
  33  * platform and NDK call it android/sync.h. A symlink from the old name to this
  34  * one exists temporarily to avoid having to change all sync clients
  35  * simultaneously. It will be removed when they've been updated, and probably
  36  * after this change has been delivered to AOSP so that integrations don't
  37  * break builds.
