Hi, As a replacement for brlocks, rcu/spinlocks are being used. For write locking spin_(un)lock_bh() are used but for read locking, whereas for read locking rcu_read_(un)lock() is used. Can some one tell me how this works? ===== Regards, Kiran Kumar Immidi __________________________________ Do you Yahoo!? Yahoo! SiteBuilder - Free web site building tool.
