f2fs: fix to avoid overflow when left shifting page offset We use following method to calculate size with current page index: size = index << PAGE_SHIFT If type of index has only 32-bits size, left shifting will incur overflow, which makes result incorrect. So let's cast index with 64-bits type to avoid such issue. Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
