Subject: [PATCH 2/2] include: linux: Remove unused macros and their defination
Date:   Sun, 14 Apr 2019 14:44:52 +0530
Message-Id: <20190414091452.22275-2-shyam.saini@amarulasolutions.com>
In-Reply-To: <20190414091452.22275-1-shyam.saini@amarulasolutions.com>
References: <20190414091452.22275-1-shyam.saini@amarulasolutions.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

In favour of FIELD_SIZEOF, lets deprecate other two similar macros
sizeof_field and SIZEOF_FIELD, and remove them completely.
