Merge tag 'block-6.14-20250131' of git://git.kernel.dk/linux
Pull more block updates from Jens Axboe:
- MD pull request via Song:
- Fix a md-cluster regression introduced
- More sysfs race fixes
- Mark anything inside queue freezing as not being able to do IO for
memory allocations
- Fix for a regression introduced in loop in this merge window
- Fix for a regression in queue mapping setups introduced in this merge
window
- Fix for the block dio fops attempting an iov_iter revert upton
getting -EIOCBQUEUED on the read side. This one is going to stable as
well
