Subject: [PATCH 06/16] tools lib traceevent: Initialize host_bigendian at tep_handle allocation
Date: Tue,  8 Jan 2019 16:59:00 -0300	[thread overview]
Message-ID: <20190108195910.17726-7-acme@kernel.org> (raw)
In-Reply-To: <20190108195910.17726-1-acme@kernel.org>

From: Tzvetomir Stoyanov <tstoyanov@vmware.com>

This patch initializes the host_bigendian member of the tep_handle
structure with the byte order of the current host, when this handler is
created - in tep_alloc() API. We need this in order to remove the
tep_set_host_bigendian() API.
