Subject: Monitor: don't get confused if utime is never set.
X-Git-Tag: mdadm-3.0~6
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4736b5dc7740ff38064c33b2460c1ee5c9aafa82;p=thirdparty%2Fmdadm.git

Monitor: don't get confused if utime is never set.

externally managed arrays do not (currently) cause utime in
GET_ARRAY_INFO to be updated.  So if it is zero, just assume the
current time.
This will cause GET_DISK_INFO to be called more often, but as we do
the scan only every 60 seconds normally, a few extra syscalls isn't
going to make a big difference.
