Subject: A beginner spinlock question
Date: Fri, 29 Aug 2003 10:52:00 +0200 [thread overview]
Message-ID: <3F4F1430.7050604@yahoo.it> (raw)
Hi All,
I'm writing my first "match" module for iptables.
I use spin_lock_bh()/spin_unlock_bh() functions for mutex between BHs.
My problem:
- I include <linux/spin_lock.h> for mutex functions declaration
- On Red Hat 9.0 with its 2.4.20-8 (redhat) kernel the compilation
procedure goes all right.
- If I compile my module with 2.4.21 original (Linus) kernel I get this
messages:
warning: implicit declaration of function `local_bh_disable'
warning: implicit declaration of function `local_bh_enable'
Anybody can help Me?
Regards.
