Subject: RE: [PATCH] nscd: Move declarations used in the library out of <nscd.h>
Date: Thu, 13 Jul 2023 08:06:11 +0000	[thread overview]
Message-ID: <TYCPR01MB6963FE1B3FEA5A6D7A90BD6DEA37A@TYCPR01MB6963.jpnprd01.prod.outlook.com> (raw)
In-Reply-To: <87ilb1yxkn.fsf@oldenburg.str.redhat.com>

Dear Florian Weimer,

Thank you for your quick update.
My understanding is that we can conclude the license of glibc as LGPLv2.1
after applying your patch. Is it correct?

I hope community's consensus to apply this fix to the mainline.

Regards,
