+Subject: [PATCH] Fix: rotation-destroy-flush: fix session daemon abort if no
+ kernel module present
+
+Testing rotation-destroy-flush when no lttng kernel modules present, it would
+be failed with error message:
+
+  Error: Unable to load required module lttng-ring-buffer-client-discard
+  not ok 1 - Start session daemon
+  Failed test 'Start session daemon'
+  not ok 2 - Create session rotation_destroy_flush in -o /tmp/tmp.test_rot ...
+  ...
+
+This because test script that sets the LTTNG_ABORT_ON_ERROR environment
+variable. It's this environment variable that causes the sessiond to handle the
+kernel module loading failure as an abort rather than a warning.
+
+Using "check_skip_kernel_test" to detect whether the kernel module fails to
+load is expected or not. If the failure is expected, the script won't set that
+environment variable any more.
+
+Fixes: 3a174400
+("tests:add check_skip_kernel_test to check root user and lttng kernel modules")
+
+Upstream-Status: Submitted [https://review.lttng.org/c/lttng-tools/+/12155]
