Hi community I have a question related to the implementation of poll() in the kernel and drivers. I am implementing a driver with poll support (through file_operations::poll) and have observed that "teardown" of the pollfds is not performed if the task is killed (while task is blocked on a call to poll()). Is this intended behavior?
As file_operations::close is called it seems possible to find and remove the FD, but I cannot find any driver doing that. Since close is actually called on the driver, I would assume the intention is to clean up the driver, but I find it a little inconsistent that cleaning up the pollfds does not happen. I am using the "flat" build configuration. The beavior may be different in "protected" builds? Regards Kian
