+Subject: [PATCH] Skip /memory-monitor-psi-env-set/write-env-null test
+
+test_write_env_null sets MEMORY_PRESSURE_WATCH=/dev/null and asserts
+that no low-memory-warning signal is emitted (warning_level stays -1).
+
+This assumption does not hold. When MEMORY_PRESSURE_WATCH points at an
+existing path, GMemoryMonitorPsi opens it with O_RDWR | O_NONBLOCK and
+creates a GSource polling for G_IO_IN. /dev/null is always readable
+(reads return immediate EOF), so the source is immediately dispatchable,
+the low-memory callback fires and warning_level becomes 50, making the
+assertion (warning_level == -1) fail:
+
+  GLib-GIO:ERROR:.../gio/tests/memory-monitor-psi-env-set.c:300:
+  test_write_env_null: assertion failed (warning_level == -1): (50 == -1)
+
+Whether the spurious event is caught before the monitor is torn down
+depends on GMainContext iteration timing, so it only reproduces in
+slower environments such as QEMU system emulation on the Yocto
+autobuilders (seen on qemuarm64). The test's abort also leaves the mock
+PSI FIFO $TMPDIR/cgroup behind, which then makes the separate
+memory-monitor-psi test fail in tests_setup with "mkfifo(): File exists".
+
+Drop the test registration and the now-unused test function. The
+remaining memory-monitor-psi-env-set subtests still run.
