I was thinking of something like that:

--- a/fs/exec.c +++ b/fs/exec.c @@ -1010,6 +1010,11 @@ ssize_t read_code(struct file *file, unsigned long addr, } EXPORT_SYMBOL(read_code); +/*

• • Maps the mm_struct mm into the current task struct.
• • On success, this function returns with the mutex
• • exec_update_mutex locked.
• */

Looks OK for me.

Cool, yeah, then I will post an updated patch in a moment.

Thanks Bernd.
