From dc35d73a42291b2a68f5b9a12b2b095b82194c1f Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Tue, 26 May 2020 09:55:02 +0800 Subject: 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.
