Subject: sw_sync callback deadlock
Date: Tue, 14 Jul 2020 22:23:58 +0100 [thread overview]
Message-ID: <20200714212401.15825-1-chris@chris-wilson.co.uk> (raw)
Take 2. dma_fence_parent() relied on fence->lock pointing into the
sync_timeline which is no more, so we need a sync_pt->timeline
backpointer instead.
