Subject: [PATCH 3/2] common/xfs: work around a hang-on-stdin bug in xfs_admin 5.11
Date: Thu, 25 Mar 2021 16:20:25 -0700 [thread overview]
Message-ID: <20210325232025.GM1670408@magnolia> (raw)
In-Reply-To: <161647323173.3431002.17140233881930299974.stgit@magnolia>
From: Darrick J. Wong <djwong@kernel.org>
xfs_admin in xfsprogs 5.11 has a bug wherein a caller who specifies an
external log device forces xfs_db to be invoked, potentially with zero
command arguments. When this happens, xfs_db will wait for input on
stdin, which causes fstests to hang. Since xfs_admin is not an
interactive tool, redirect stdin from /dev/null to prevent this issue.
