Message-Id: <20190219042048.23243-2-tung.q.nguyen@dektech.com.au> Date: Tue, 19 Feb 2019 11:20:47 +0700 From: Tung Nguyen <tung.q.nguyen@...tech.com.au> To: davem@...emloft.net, netdev@...r.kernel.org Cc: tipc-discussion@...ts.sourceforge.net Subject: [tipc-discussion][net 1/2] tipc: improve function tipc_wait_for_cond() Commit 844cf763fba6 ("tipc: make macro tipc_wait_for_cond() smp safe") replaced finish_wait() with remove_wait_queue() but still used prepare_to_wait(). This causes unnecessary conditional checking before adding to wait queue in prepare_to_wait(). This commit replaces prepare_to_wait() with add_wait_queue() as the pair function with remove_wait_queue().
