From: Julien Desfossez Date: Mon, 25 Nov 2013 20:32:38 +0000 (-0500) Subject: Rename LTTng index in CTF index X-Git-Tag: v2.4.0-rc2~21 X-Git-Url: https://git.lttng.org/?p=lttng-tools.git;a=commitdiff_plain;h=50adc26400482c07210afcda8ef1d3322f75871d Rename LTTng index in CTF index Also the magic becomes a uint32_t instead of 6 chars for more aligned reads. Apart from the CTF magic changes, this patch only renames stuff so no behaviour is changed.
