[f2fs-dev] [PATCH 2/2] f2fs: no need to lock for update_inode_page all the time

As comment says, we don't need to call f2fs_lock_op in write_inode to prevent from producing dirty node pages all the time. That happens only when there is not enough free sections and we can avoid that by calling balance_fs in prior to that. Signed-off-by: Jaegeuk Kim ---
