+Subject: [PATCH] fix: 'random' tracepoints removed in stable kernels
+
+The upstream commit 14c174633f349cb41ea90c2c0aaddac157012f74 removing
+the 'random' tracepoints is being backported to multiple stable kernel
+branches, I don't see how that qualifies as a fix but here we are.
+
+Use the presence of 'include/trace/events/random.h' in the kernel source
+tree instead of the rather tortuous version check to determine if we
+need to build 'lttng-probe-random.ko'.
