entry->proc_fops is a pointer to struct file_operations. When we call create_proc_entry(...), it pointis to proc_file_operations, deep in fs/proc/generic.c. By adding a 'poll' member to this struct we effectively force the 'poll' member on every file in /proc, which is wrong (they all fail select(...) calls). This patch changes a copy of entry->proc_fops and reassigns it rather than changing the original member. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
