Subject: [PATCH 4.9 095/109] dma-buf/sw_sync: move timeline_fence_ops around
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gustavo Padovan <gustavo.padovan@...labora.com>
commit 150b6a9d7d6fffb95c0a5349960a10569e8218b5 upstream.
We are going to use timeline_fence_signaled() in a internal function in
the next commit.
