I think there is no upstream commit because this is a bug in SUSE specific patches.
Yes, you are right. Thanks. Reassigning to Mel who is working on SoN fixes currently. And adding Suresh who committed those patches. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
