From 38aaf8090d34b623b7919d8c933f6e938c9bf44b Mon Sep 17 00:00:00 2001 From: Huang Ying Date: Thu, 8 Sep 2011 14:00:46 +0800 Subject: irq_work: Use llist in the struct irq_work logic Use llist in irq_work instead of the lock-less linked list implementation in irq_work to avoid the code duplication.
