Hi Jens, 

I am so sorry for this problem.

Hi Jens, 

Please consider pulling the following changes for md-next on top of your
for-6.5/block branch. The major changes are:

1. Deprecate bitmap file support, by Christoph Hellwig;
2. Fix deadlock with md sync thread, by Yu Kuai;
3. Refactor md io accounting, by Yu Kuai.

This is quite a lot on the day that I prepare pull requests for the
merge window... I've said this many times before, but just to state this
in completeness, maybe it'll benefit others too:

1) Major changes for the next release should be sent to me _at least_ 1
  week prior to the merge window opening. That way it gets some decent
  soak time in linux-next before heading upstream.

I am aware of the rule. A couple reasons caused a late PR this time:

1. Set #1 and set #3 are relatively new, especially set #3, which was
   first sent earlier this week. Set #2 is older, but there was more
   discussions on it until recently. (It is still my fault not pushing
   on set #2 sooner). 

2. I wasn't very sure whether there will be a rc8. The announcement for
   rc7 didn't state it clearly. (Shall I assume there is no rc8 unless
   Linus states it clearly?)

3. I was hoping to group more patches into one PR. I guess this was the 
   biggest mistake, especially when it is close to the merge window.

2) Minor fixes, either for major pulls that already went into my next
  branch or just fixes in general, can be sent anytime and I'll shove
  them into the appropriate branch.

When bigger stuff gets sent this late, then I have two choices: reject
them and tell you to send it in for the next version, or setup a new
branch just for this so I can send it to Linus in a later pull in the
merge window. Neither of those two options are great - the first one
delays you by a release, the second one creates more churn and hassle
for me.

I will prepare another PR with just fixes. 

Christoph, 

Please let me know if you need set #1 (deprecate file bitmap) to 
unblock other work. Otherwise, we will delay it until 6.6. 

Thanks,
Song
