From e8d61a7488d06aba3e7226e3536a6a6e14391ce8 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Thu, 24 Oct 2013 15:08:28 +0800 Subject: f2fs: remove redundant set_page_dirty from write_compacted_summaries Previously, set_page_dirty is called every time after writting one summary info into compacted summary page, To avoid redundant set_page_dirty, we only call set_page_dirty before release page.
