Hi Linus, Here are the initial set of block updates for the 6.13 kernel. Fairly quiet round this time. This request contains: - NVMe updates via Keith - Use uring_cmd helper (Pavel) - Host Memory Buffer allocation enhancements (Christoph) - Target persistent reservation support (Guixin) - Persistent reservation tracing (Guixen) - NVMe 2.1 specification support (Keith) - Rotational Meta Support (Matias, Wang, Keith) - Volatile cache detection enhancment (Guixen) - MD updates via Song - Maintainers update - raid5 sync IO fix - Enhance handling of faulty and blocked devices - raid5-ppl atomic improvement - md-bitmap fix - Support for manually defining embedded partition tables - Zone append fixes and cleanups - Stop sending the queued requests in the plug list to the driver ->queue_rqs() handle in revers order. - Zoned write plug cleanups - Cleanups disk stats tracking and add support for disk stats for passthrough IO - Add preparatory support for file system atomic writes - Add lockdep support for queue freezing. Already found a bunch of issues, and some fixes for that are in here. More will be coming. - Fix race between queue stopping/quiescing and IO queueing - ublk recovery improvements - Fix ublk mmap for 64k pages - Various fixes and cleanups Note that merging this will throw a simple merge conflict drivers/nvme/host/core.c due to the SRCU iteration fix that got merged late in the 6.12 cycle. I won't bother with noting how to resolve it here, as it's about as simple as it gets. Please pull!
