Re: [Linux-diag-devel] [patch 0/1] [ppc64-diag] Fixes to comply with hardened build flags used by ubuntu and debian

[Aruna B. <ar...@li...>]

Hi,

If there is only one patch then no need to send it in the series format
please incorporate the patch description in the header of the same patch.
As the cover letter is discarded when the patch is committed to git tree.

Regards,
Aruna
