From f9f7bb9e0a0ca33f65a3deae9ec5e07266908fc5 Mon Sep 17 00:00:00 2001 From: Naveen Kumar Parna Date: Tue, 22 Jan 2019 19:14:02 +0530 Subject: [PATCH] mbcs: add .owner to mbcs struct file_operations MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Without ".owner = THIS_MODULE" it is possible to crash the kernel by unloading the mbcs module while someone works with the file. Fix this by initializing the ‘struct file_operations' ->owner with THIS_MODULE.
