And nothing of significance changed, that was the point. The debug name of the context was changed to avoid having the self-referential problem of how to get the ctx-id but set the ctx->name prior to inserting the id into the context; which could have been pushed under the idr_lock, but I choose to take the course of removing the extra user_handle as evidenced by the next few patches. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
