I'd like to add that we are seeing this problem with singlepath installations

With multipath, it may happen that the same device is passed
to enclosure_add_device() multiple times and that the enclosure_add_links()
function fails to create the symlinks because the device's sysfs
directory entry is still NULL.
In this case, the links will never be created because all the subs

to enclosure_add_device() multiple times and that the enclosure_add_links()
function fails to create the symlinks because the device's sysfs
directory entry is still NULL.
In this case, the links will never be created because all the subs
