[GIT PULL] Block driver updates for 5.18-rc1

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Linus,

On top of the core block updates for the 5.18-rc1 merge window, here are
the driver updates for this merge window. In detail:

- NVMe updates via Christoph:
	- add vectored-io support for user-passthrough (Kanchan Joshi)
	- add verbose error logging (Alan Adamson)
	- support buffered I/O on block devices in nvmet (Chaitanya Kulkarni)
	- central discovery controller support (Martin Belanger)
	- fix and extended the globally unique idenfier validation
	  (Christoph)
	- move away from the deprecated IDA APIs (Sagi Grimberg)
	- misc code cleanup (Keith Busch, Max Gurtovoy, Qinghua Jin,
	  Chaitanya Kulkarni)
	- add lockdep annotations for in-kernel sockets (Chris Leech)
	- use vmalloc for ANA log buffer (Hannes Reinecke)
	- kerneldoc fixes (Chaitanya Kulkarni)
	- cleanups (Guoqing Jiang, Chaitanya Kulkarni, Christoph)
	- warn about shared namespaces without multipathing (Christoph)

- MD updates via Song with a set of cleanups (Christoph, Mariusz, Paul,
  Erik, Dirk)

- loop cleanups and queue depth configuration (Chaitanya)

- null_blk cleanups and fixes (Chaitanya)

- Use descriptive init/exit names in virtio_blk (Randy)

- Use bvec_kmap_local() in drivers (Christoph)

- bcache fixes (Mingzhe)

- xen blk-front persistent grant speedups (Juergen)

- rnbd fix and cleanup (Gioh)

- Misc fixes (Christophe, Colin)

This will throw a merge conflict in drivers/nvme/target/configfs.c,
resolution is just to delete the two discovery helpers and the configfs
attribute, basically everything in the conflict section. This is due to
conflicting with a last minute revert in 5.17.

Please pull!
