Subject: [PATCH 2/2] unshare system call patch - needed to test pam_namespace
Date: Fri, 15 Jul 2005 16:09:17 -0400 [thread overview]
Message-ID: <42D817ED.9000009@us.ibm.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 234 bytes --]
Here is part of the unshare system call patch. This one implements
system call for i386 arch. I do have suggestion for code change for
some other architectures, but since I haven't tested them I haven't
included in the patch.
