Subject: [PATCH 0/2] rv: Fix wrong type cast
Date: Sun, 27 Jul 2025 19:31:11 +0200 [thread overview]
Message-ID: <cover.1753625621.git.namcao@linutronix.de> (raw)
Hi,
After my previous rv simplification series:
https://lore.kernel.org/linux-trace-kernel/cover.1753378331.git.namcao@linutronix.de/T/#t
Some RV's available/enabled reactors/monitors files do not work anymore:
root@yellow:~# cat /sys/kernel/tracing/rv/available_monitors
nop: �������`������� ���������Z������u�����-s�����
nop:���������������� �������@>H�����
nop:
��������
��������8�������:��������
`���������������
root@yellow:~# cat /sys/kernel/tracing/rv/available_reactors
��������8�������
P�������x�������
8����������������^�����81s������I?�������������8�������
It turned out that there has been a type cast mistake in RV all this time,
but it still happened to work. Due to the recent refactor, the mistaken
type cast got "promoted" and became a real problem.
This series fixes up this type cast.
