[PATCH 1/1] kdump: append uts_namespace.name offset to VMCOREINFO

[HAGIO KAZUHITO(萩尾 一仁)]

Hi Dave,

sorry to bother you.  We need this kernel patch to fix a makedumpfile issue
with the current linux-next.  Should we send this to the addresses below, right?
I'm not sure whether they are enough.

Alex,

Thanks for the patch.  Since this patch is for kernel, it needs to be sent
to kernel maintainers and mailing lists, and I think you can get their
addresses with scripts/get_maintainer.pl in the kernel tree.

$ scripts/get_maintainer.pl /tmp/a.patch 
Dave Young <dyoung at redhat.com> (maintainer:KDUMP)
Baoquan He <bhe at redhat.com> (maintainer:KDUMP)
Vivek Goyal <vgoyal at redhat.com> (reviewer:KDUMP)
kexec at lists.infradead.org (open list:KDUMP)
linux-kernel at vger.kernel.org (open list)

Thanks,
Kazu
