From: Raphaël Beamonte Date: Fri, 15 Nov 2013 00:58:35 +0000 (-0500) Subject: Remove the utils_resolve_relative function that is not useful anymore X-Git-Tag: v2.4.0-rc1~2 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=635eb1df606e714f3d5cdded93b9c663b0e8e4c3;p=lttng-tools.git Remove the utils_resolve_relative function that is not useful anymore As all of the work is now done in utils_partial_realpath and utils_expand_path, utils_resolve_relative is not necessary anymore and should be deleted from the sources.
