Subject: [PATCH 4.4 014/104] f2fs: use crc and cp version to determine roll-forward recovery
Date: Thu, 24 Jan 2019 20:19:03 +0100 [thread overview]
Message-ID: <20190124190156.414555113@linuxfoundation.org> (raw)
In-Reply-To: <20190124190154.968308875@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jaegeuk Kim <jaegeuk@kernel.org>
commit a468f0ef516fda9c7d91bb550d458e853d76955e upstream.
Previously, we used cp_version only to detect recoverable dnodes.
In order to avoid same garbage cp_version, we needed to truncate the next
dnode during checkpoint, resulting in additional discard or data write.
If we can distinguish this by using crc in addition to cp_version, we can
remove this overhead.
There is backward compatibility concern where it changes node_footer layout.
So, this patch introduces a new checkpoint flag, CP_CRC_RECOVERY_FLAG, to
detect new layout. New layout will be activated only when this flag is set.
