From: David Goulet Date: Mon, 25 Nov 2013 19:55:57 +0000 (-0500) Subject: Fix: create a fast and a long UST snapshot test X-Git-Tag: v2.4.0-rc2~27 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=1d20c959e3aa1a9a205fd7fff2d912b6bada1d23;p=lttng-tools.git Fix: create a fast and a long UST snapshot test The fast one does 10 snapshots where the long one keeps the 1000 original value. The make check only executes the fast one.
