trace-cmd: Add blktrace_api compatibility for TC_BARRIER
Newer kernels replace TC_BARRIER with TC_FLUSH. Ensure trace-cmd can build regardless of the linux-kernel-headers version. This is intended as a stop-gap to get the builds working again. A proper fix will need to be discussed with the trace-cmd community. RP: Tweaked the SRC_URI to remove unnecessary path and added PR bump Signed-off-by: Darren Hart <dvhart@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
