Date: Thu, 25 Dec 2003 20:15:19 +0000	[thread overview]
Message-ID: <marc-linux-hotplug-107238337211654@msgid-missing> (raw)

[-- Attachment #1: Type: text/plain, Size: 181 bytes --]


Attached is a patch for udev-add.c to ignore empty symlink string parts.
Issue was brought up by ide-devfs.sh with only one symlink returned, while two are expected.

thanks,
Kay
