This patch series introduces in the first change a new UFS ioctl, allowing user-space to send UFS queries and retrieve information from them. In addition, the other three patches add utilities to support debugging efforts and supply information that will help analysis of issue: UFS trace events, dump host controller registers and requests descriptors on failures, several statistics.
