Pavel Begunkov Date: Fri Nov 15 16:54:38 2024 +0000 io_uring: fortify io_pin_pages with a warning We're a bit too frivolous with types of nr_pages arguments, converting it to long and back to int, passing an unsigned int pointer as an int pointer and so on. Shouldn't cause any problem but should be carefully reviewed, but until then let's add a WARN_ON_ONCE check to be more confident callers don't pass poorely checked arguents.
