From 4515d08a742c76612b65d2f47a87d12860519842 Mon Sep 17 00:00:00 2001 From: Marco Pagani Date: Thu, 21 Dec 2023 17:58:47 +0100 Subject: [PATCH] kernel/module: improve documentation for try_module_get() The sentence "this call will fail if the module is already being removed" is potentially confusing and may contradict the rest of the documentation. If one tries to get a module that has already been removed using a stale pointer, the kernel will crash.
