If anyone has any objections, please let me know. ------------------ From: Chris Wilson commit e659d14ed48096f87a678e7ebbdf286a817b4d0e upstream. If we fail to unbind the vma (due to a signal on an active buffer that needs to be moved for the next execbuf), then we need to clear the persistent tracking state we setup for this execbuf.
