Date: Tue, 26 May 2020 09:55:02 +0800 From: Chao Yu <yuchao0@...wei.com> To: <jaegeuk@...nel.org> CC: <linux-f2fs-devel@...ts.sourceforge.net>, <linux-kernel@...r.kernel.org>, <chao@...nel.org>, Chao Yu <yuchao0@...wei.com> Subject: [PATCH] f2fs: compress: don't compress any datas after cp stop While compressed data writeback, we need to drop dirty pages like we did for non-compressed pages if cp stops, however it's not needed to compress any data in such case, so let's detect cp stop condition in cluster_may_compress() to avoid redundant compressing and let following f2fs_write_raw_pages() drops dirty pages correctly.
