That allow us to remove .has_signaled() from timeline_ops as we can directly compare using timeline->value and fence->seqno in sync.c Signed-off-by: Gustavo Padovan --- drivers/staging/android/sw_sync.c | 16 ++-------------- drivers/staging/android/sync.c | 15 +++++++-------- drivers/staging/android/sync.h | 14 +++++--------- 3 files changed, 14 insertions(+), 31 deletions(-) diff --git a/drivers/staging/android/sw_sync.c b/drivers/staging/android/sw_sync.c index af39ff5..428e22c 100644 --- a/drivers/staging/android/sw_sync.c +++ b/drivers/staging/android/sw_sync.c @@ -30,7 +30,7 @@ struct fence *sw_sync_pt_create(struct sw_sync_timeline *obj, u32 value) struct sw_sync_pt *pt; pt = (struct sw_sync_pt *) - sync_pt_create(&obj->obj, sizeof(struct sw_sync_pt)); + sync_pt_create(&obj->obj, sizeof(struct sw_sync_pt), value); pt->value = value; @@ -38,15 +38,6 @@ struct fence *sw_sync_pt_create(struct sw_sync_timeline *obj, u32 value) } EXPORT_SYMBOL(sw_sync_pt_create); -static int sw_sync_fence_has_signaled(struct fence *fence) -{ - struct sw_sync_pt *pt = (struct sw_sync_pt *)fence; - struct sw_sync_timeline *obj = - (struct sw_sync_timeline *)fence_parent(fence); - - return (pt->value > obj->value) ?
