or may be something like below? can save us some cycles.

remove this calculation

-       offset = sector & (SECTORS_PER_PAGE - 1) << SECTOR_SHIFT;


and pass 0 to zram_bvec_rw()

-       err = zram_bvec_rw(zram, &bv, index, offset, is_write);
+       err = zram_bvec_rw(zram, &bv, index, 0, is_write);
