Subject: [PATCH 2/2] jffs2: Add sync to underlying mtd device when file system is synced
Date: Fri, 3 May 2019 15:13:38 -0500 [thread overview]
Message-ID: <1556914418-40288-2-git-send-email-clayton.shotwell@rockwellcollins.com> (raw)
In-Reply-To: <1556914418-40288-1-git-send-email-clayton.shotwell@rockwellcollins.com>
Need to ensure the underlying flash does not cache anything even though
the file system thinks it's synced back.
