Subject: ddf: Don't consider 'dl' entries with state_fd < 0
X-Git-Tag: mdadm-3.1.5~14
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=77632af90637004deac013d1716727b15094b3ee;p=thirdparty%2Fmdadm.git

ddf: Don't consider 'dl' entries with state_fd < 0

These have been marked as invalid (recently failed) so
don't trust the major/minor associated with them.
