[PATCH blktests v3 2/2] md: add regression test for "md/md-bitmap: fix writing non bitmap pages"

[Shinichiro Kawasaki]

Hi Ofir, thank you for this v3 series. The two patches look good to me, except
one unclear point below.

The cover letter of the series says that the new test case is the regression
test for the patch "md/md-bitmap: fix writing non bitmap pages". On the other
hand, the comment above says that this test case is for the two patches. Which
is correct? (Or which is more accurate?)

When I ran this test case, it failed on the kernel v6.10, which is expected.
Then I applied the 1st patch "md/md-bitmap: fix writing non bitmap pages" only
to the v6.10 kernel, and the test case passed. It passed without the 2nd patch
"nvme-tcp: use sendpages_ok() instead of sendpage_ok()". So, I'm not sure if
this test case is the regression test for the 2nd patch.
