From 06fbcb104ad16c22eb5718ae598b306c777be8af Mon Sep 17 00:00:00 2001 From: Peter Oberparleiter Date: Mon, 10 Apr 2006 22:53:46 -0700 Subject: [PATCH] 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.
