You should have listened of Matthew and submit separate minimal
bug-fixing patches instead of posting huge patches which move code
around, change semantics and hidden somewhere deep within fix some bug
(and then introduce new bugs).

There was exactly one review, and no, you were not "happy to rework
and to make any patch more better" - you openly rejected Matthew's
review.

Your argument only appears to sound right, but it is detached from the
reality I'm living in.

Your patches made Ceph less stable.  6.14 had one Ceph-related crash
every other week, but 6.15 with your patches made all servers crash
within hours.

The point is: the Linux kernel was better without your patches.  Your
patches may have fixed a bug, but have introduced a dozen new bugs,
including one that very quickly crashes the whole kernel, one that was
really obvious enough, just nobody cared enough to read deeply enough
after you rejected Matthew's review.  Too bad no maintainer stopped
you!

Of course, the bug that was fixed by your patch set should be fixed -
but not the way you did it.  Every aspect of your approach to fixing
the bug was bad.

The best way forward for you would be to revert this patch set and
write a minimal patch that only fixes the bug.  If you want to be
helpful here, please give this a try.
