Subject: [PATCH 1/6] trace-cmd: Initialize host_bigendian at tep_handle allocation
Date: Wed, 30 Jan 2019 12:44:20 +0200
Message-ID: <20190130104425.8813-2-tstoyanov@vmware.com> (raw)
In-Reply-To: <20190130104425.8813-1-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.
