From 4671a1322052425afa38fcb7980d2fd2bb0fc99b Mon Sep 17 00:00:00 2001 From: Richard Kennedy Date: Mon, 1 Mar 2010 10:57:22 +0100 Subject: block: don't access jiffies when initialising io_context As the comment says the initial value of last_waited is never used, so there is no need to initialise it with the current jiffies. Jiffies is hot enough without accessing it for no reason.
