Subject: test_cephfs_shell: initialize stderr for run_cephfs_shell_cmd()
X-Git-Tag: v15.1.0~893^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=bafef71e49c62f221ce421ac51b2b74c90afea34;p=ceph.git

test_cephfs_shell: initialize stderr for run_cephfs_shell_cmd()

Since teuthology initializes stderr to None by default, absence of this
breaks the tests accessing stderr of commands executed within the test
when the execution is using teuthology.
