Subject: Test fix: ignore stderr when generating random string
X-Git-Tag: v2.7.2~10
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=81a8f4ac80a32277cab60d6d5269a9b454c8f2a0;p=lttng-tools.git

Test fix: ignore stderr when generating random string

tr often reports a broken pipe when the head command exits
(after having received enough characters) which pollutes the
test output.
