Previously, we supported to account FS_CDATA_READ_IO type IO only, in this patch, it adds to account more type IO for compressed file: - APP_BUFFERED_CDATA_IO - APP_MAPPED_CDATA_IO - FS_CDATA_IO - APP_BUFFERED_CDATA_READ_IO - APP_MAPPED_CDATA_READ_IO Signed-off-by: Chao Yu <chao.yu@oppo.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
