[PATCH 0/2] rv: Fix wrong type cast

Posted by Nam Cao 2 months, 1 week ago

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.
