From 7921b35c5fcf300ebd860e3e7894c692c9547838 Mon Sep 17 00:00:00 2001 From: "Kashyap, Desai" Date: Wed, 17 Mar 2010 16:21:33 +0530 Subject: [PATCH] [SCSI] mpt2sas: Corrected time stamp incorrect timestamp on 32 bit platforms: The upper 32 bit of the timestamp was getting truncated when converting seconds to milliseconds, which was due to the variable being long. To fix the problem, the variable needs to be u64. Also the microseconds conversion to milliseconds was incorrect; it should be divide by 1000 instead of divide by 8.
