Subject: Patch from Stephan Metzmacher to add default arguments to lp_parm() smb.conf
X-Git-Url: http://git.samba.org/?a=commitdiff_plain;h=1f008c1203b082039a9824c186fa2eda730c6f46;p=metze%2Fsamba%2Fwip.git

Patch from Stephan Metzmacher to add default arguments to lp_parm() smb.conf
parameters. Does not break binary compatibility with older modules.
(This used to be commit 147c4d56d873a20a49194c5b036a3694299b1b48)
