From: Chris Wilson Date: Thu, 29 Jun 2017 12:59:28 +0000 (+0100) Subject: dma-buf/sw-sync: sync_pt is private and of fixed size X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3b52ce44e720c240afc4c4b03140d7b7811b23bd;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git dma-buf/sw-sync: sync_pt is private and of fixed size Since sync_pt is only allocated from a single location and is no longer the base class for fences (that is struct dma_fence) it no longer needs a generic unsized allocator.
