From 79e35dc3c23dd2ac9f8681361026c82b71a0b006 Mon Sep 17 00:00:00 2001 From: Huang Ying Date: Sat, 12 Jul 2014 20:10:00 +0800 Subject: [PATCH] f2fs: add f2fs_balance_fs for direct IO Otherwise, if a large amount of direct IO writes were done, the segment allocation may be failed because no enough segments are gced. Changes: v2: add f2fs_balance_fs into __get_data_block instead of f2fs_direct_IO.
