Subject: [PATCH] blktrace: pdu_buf of pc events should be unsigned
Date: Mon, 11 May 2009 14:33:23 +0800 [thread overview]
Message-ID: <4A07C6B3.9080802@cn.fujitsu.com> (raw)
I got this:
8,0 1 305.417782332 2037 I R 32 (ffffff9e 10 00 ...) [bash]
It should be:
8,0 1 305.417782332 2037 I R 32 (9e 10 00 ...) [bash]
[ Impact: fix output of pc events ]
