When DAX calls ext2_get_block() and the file offset points to a hole we
currently don't set bh_result->b_size. When we re-enable PMD faults DAX
will need bh_result->b_size to tell it the size of the hole so it can
decide whether to fault in a 4 KiB zero page or a 2 MiB zero page.
For ext2 we
When DAX calls ext2_get_block() and the file offset points to a hole we
currently don't set bh_result->b_size. When we re-enable PMD faults DAX
will need bh_result->b_size to tell it the size of the hole so it can
decide whether to fault in a 4 KiB zero page or a 2 MiB zero page.
