Subject: [PATCH v2 1/1] kdump: append uts_namespace.name offset to VMCOREINFO
Date: Thu, 24 Sep 2020 14:46:47 +0200	[thread overview]
Message-ID: <20200924124647.300080-1-egorenar@linux.ibm.com> (raw)

The offset of the field 'init_uts_ns.name' has changed
since

commit 9a56493f6942c0e2df1579986128721da96e00d8
Author: Kirill Tkhai <ktkhai@virtuozzo.com>
Date:   Mon Aug 3 13:16:21 2020 +0300

    uts: Use generic ns_common::count

Link: https://lore.kernel.org/r/159644978167.604812.1773586504374412107.stgit@localhost.localdomain

Make the offset of the field 'uts_namespace.name' available
in VMCOREINFO because tools like 'crash-utility' and
'makedumpfile' must be able to read it from crash dumps.
