Subject: [patch 5/9] s390: increase cio_trace debug event size.
Date: Mon, 3 Apr 2006 19:22:38 +0200 [thread overview]
Message-ID: <20060403172238.GE11049@skybase> (raw)
From: Peter Oberparleiter <peter.oberparleiter@de.ibm.com>
[patch 5/9] s390: increase cio_trace debug event size.
Debugging events in cio_trace/hex_ascii are truncated for some trace
entries. Increase trace event size to 16 bytes to cover longer text
events, make CIO_HEX_EVENT an inline function that loops to cover bigger
hex events.
