Merge tag 'for-6.10/block-20240511' of git://git.kernel.dk/linux
Pull block updates from Jens Axboe:
- Add a partscan attribute in sysfs, fixing an issue with systemd
relying on an internal interface that went away.
- Attempt #2 at making long running discards interruptible. The
previous attempt went into 6.9, but we ended up mostly reverting it
as it had issues.
- Remove old ida_simple API in bcache
- Support for zoned write plugging, greatly improving the performance
on zoned devices.
- Remove the old throttle low interface, which has been experimental
since 2017 and never made it beyond that and isn't being used.
- Remove page->index debugging checks in brd, as it hasn't caught
anything and prepares us for removing in struct page.
- MD pull request from Song
- Don't schedule block workers on isolated CPUs
