[GIT PULL] md-6.9 20240305

[Song Liu]

Hi Jens, 

Please consider pulling the following fixes for md-6.9 on top of your 
for-6.9/block branch. This set fixes two issues:

1. dmraid regression since 6.7 kernels. This issue was initially 
  reported in [1]. This set of fix has been reviewed and tested by
  md and dm folks. 

2. raid5 hang since 6.7 kernel, reported in [2]. We haven't got a 
  better fix for this issue yet. This revert is a workaround. It has
  been applied to 6.7 stable kernels [3], and proved to be affective.
  We will look more into this issue for a better fix. 

Note: Some recent fixes were shipped via the md-6.8 branch, so the 
md-6.9 branch doesn't have all the fixes. I tested that there is no 
conflict between these fixes and those shipped earlier. I run the 
tests with upstream kernel and changes in block tree and md tree 
(v6.8-rc7 + for-6.9/block + md-6.9).

Thanks,
Song

Hi Song,

can you also send the queue limits changes on?  I'd really like to
have all non-scsi queue limits updates in 6.9 and have been working
hard on that.

Sure! Here it is.

Jens, could you please also pull the following changes.

This set by Christoph converts md to the atomic queue limits update API.

Thanks,
Song

You could've just replied to the thread with "Reviewed-by" like I
suggested, would've saved both of us some time! Anyway, pulled.
