Subject: [PATCH] net: Avoid problems with bonding and device rename
Date: Wed, 14 May 2008 17:03:16 -0700 [thread overview]
Message-ID: <20080514170316.672f809d@extreme> (raw)
See: http://bugzilla.kernel.org/show_bug.cgi?id=10698
The use of /sys/class/net/bonding_masters was a poor ABI choice
that now we have to live with. Best choice is to just block other
usage of that name.
