Subject: [PATCH v4 11/11] selftests/ftrace: Change stderr redirection for probe error_log testcase
Date: Fri, 22 Mar 2019 10:34:37 -0500 [thread overview]
Message-ID: <ce51abd8585b775fd98e31e5feb1b1505483312f.1553268041.git.tom.zanussi@linux.intel.com> (raw)
In-Reply-To: <cover.1553268040.git.tom.zanussi@linux.intel.com>
In-Reply-To: <cover.1553268040.git.tom.zanussi@linux.intel.com>
From: Tom Zanussi <tom.zanussi@linux.intel.com>
On my system, /bin/sh is symlinked to dash, which doesn't understand
the >& syntax, so the kprobe and uprobe error cases fail, with this in
the log:
./ftracetest: 26: tools/testing/selftests/ftrace/test.d/kprobe/kprobe_syntax_errors.tc:
Syntax error: Bad fd number
Changing >& to 2> does work though, and should work in any shell.
