Hi all.
1. bdrv_dirty_iter_next_area don't use hbitmap_next_zero and uses
inefficient loop instead. Let's improve it.
2. bdrv_dirty_iter_next_area don't handle unaligned offset and
max_offset correctly. I'm not sure that it is a real bug. But if it is,
we need these series in 3.0.
Details are in 03 commit message.

Add bytes parameter to the function, to limit searched range.

The function alters bdrv_dirty_iter_next_area(), which is wrong and
less efficient (see next commit for description).

Use bdrv_dirty_bitmap_next_dirty_area() instead of
bdrv_dirty_iter_next_area(), because of the following problems of
bdrv_dirty_iter_next_area():
1. Using HBitmap iterators we should carefully handle unaligned offset,
as first call to hbitmap_iter_next() may return a value less than
original offset (actually, it will be original offset rounded down to
bitmap granularity). This handling is not done in
do_sync_target_write().
2. bdrv_dirty_iter_next_area() handles unaligned max_offset
incorrectly:
look at the code:
if (max_offset == iter->bitmap->size) {
/* If max_offset points to the image end, round it up by the
* bitmap granularity */
gran_max_offset = ROUND_UP(max_offset, granularity);
} else {
gran_max_offset = max_offset;
}
ret = hbitmap_iter_next(&iter->hbi, false);
if (ret < 0 || ret + granularity > gran_max_offset) {
return false;
}
and assume that max_offset != iter->bitmap->size but still unaligned.
if 0 < ret < max_offset we found dirty area, but the function can
return false in this case (if ret + granularity > max_offset).
3. bdrv_dirty_iter_next_area() uses inefficient loop to find the end of
the dirty area. Let's use more efficient hbitmap_next_zero instead
(bdrv_dirty_bitmap_next_dirty_area() do so)

Can @bytes (or rather, @start + @bytes) exceed the remaining bitmap
length (in which case it is silently truncated to the remaining length)?

This computation can overflow if bytes is too large...

and only now are you asserting that bytes was in range. You should at
least document that bytes must be in range, and while I don't see any
memory dereferences dependent on a potentially bogus end_bit value, it
may also be worth hoisting the assert sooner in the function.
