From fe76b796fc5194cc3d57265002e3a748566d073f Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Thu, 30 Jun 2016 18:40:10 -0700 Subject: f2fs: introduce f2fs_set_page_dirty_nobuffer This patch adds f2fs_set_page_dirty_nobuffer() copied from __set_page_dirty_buffer. When appending 4KB blocks in f2fs on pmem with multiple cores, this improves the overall performance.
