Safe registration of procfs entries in LKM

Hello, I was wondering how a loadable (and specifically unloadable) kernel module can safely provide a procfs entry. The procfs code switched from `struct file_operations`, which has a `struct module *owner` member to using `struct proc_ops`, which doesn't. This member allowed the core code to `try_module_get()` the module before calling the operation, so that we can avoid calling it if the module is in the process of being removed and increase the module use count to prevent the module from being unloaded while the open file description exists. The procfs code did previously use `struct file_operations`, but it looks like it didn't honour this member then. Does this mean procfs is not meant for loadable modules? Thanks, Torin
