The Linux kernel commit 14c174633f349 ("random: remove unused tracepoints")
removed unused tracepoints and has been backported to stable Linux kernel
releases. This causes build failure of lttng-modules:
"
lttng-modules-2.11.6/probes/lttng-probe-random.c:18:10: fatal error: trace/events/random.h: No such file or directory
| 18 | #include <trace/events/random.h>
| | ^~~~~~~~~~~~~~~~~~~~~~~
| compilation terminated.
"
Backport patches from lttng-modules master branch to address the build
failure on all of Linux 5.18.y, 5.15.y and 5.10.y kernel versions.

+Subject: [PATCH 19/19] 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'.

Do you want a V2 with this updated commit message ?
(or, can Steve add this line when applying?)
