Subject: [PATCH 3/3] raid: substitute empty_zero_page with helper ZERO_PAGE(0)
Date: Tue, 18 Oct 2022 23:57:55 +0200 [thread overview]
Message-ID: <20221018215755.33566-3-giulio.benetti@benettiengineering.com> (raw)
In-Reply-To: <20221018215755.33566-1-giulio.benetti@benettiengineering.com>
Not all zero page implementations use empty_zero_page global pointer so
let's substitute empty_zero_page occurence with helper ZERO_PAGE(0).
