From 3eaf840e0b0046f56602c524c7ba58a82f5526c5 Mon Sep 17 00:00:00 2001 From: "Jun'ichi \"Nick\" Nomura" Date: Wed, 1 Feb 2006 03:04:53 -0800 Subject: [PATCH] device-mapper disk statistics: timing Record I/O timing statistics The start time is added to struct dm_io, an existing structure allocated privately internally within dm and attached to each incoming bio. We export disk_round_stats() from block/ll_rw_blk.c instead of creating a private clone.
