Detailed Description

A filter which, if passed to for_each_block_in_reverse, calls the provided visitor only for the blocks which were modified by this mtr.

Note: the pages are considered to be modified if they were X or SX latched, or made_dirty_with_no_latch, so there could be false-positives. Note: as a side effect made_dirty_with_no_latch gets cleared.
