From 976e4c50aea111bc7193b48950a3b0c8bc0a25ff Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Mon, 15 Sep 2014 19:32:16 -0700 Subject: [PATCH] f2fs: update i_size when __allocate_data_block The f2fs_direct_IO uses __allocate_data_block, but inside the allocation path, we should update i_size at the changed time to update its inode page. Otherwise, we can get wrong i_size after roll-forward recovery.
