fabio-d / block-led-trigger Goto Github PK

On Linux 6.5.x, the module compiles and loads, but LED is not triggered. Worked fine up until 6.4.x.

Hi, I would like to use this module on a router running openwrt. Since one can't build modules on the router itself due to space restrictions, I'd need to have it compiled into the kernel during openwrt build process.

Hi. I don't know how to use the builtin kernel trigger you mention, so I tried your code instead. It won't build on 5.9, the messages upon compilation are:
