[GIT PULL] NVMe updates for Linux 4.13

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

 



Hi Jens,

here is a large chunk of NVMe updates for 4.13.  I don't think we
are quite done for this merge window yet, but I'd like to get
this large batch into your tree and linux-next.

Highlights:

 - UUID identifier support from Johannes
 - Lots of cleanups from Sagi
 - Host Memory Buffer support from me

And lots of cleanups and smaller fixes of course.

Note that the UUID identifier changes are based on top of the uuid tree.
I am the maintainer of that tree and will send it to Linus as soon as
4.12 is released as various other trees depend on it as well (and the
diffstat includes those changes unfortunately)


The following changes since commit f06345add95f388519e83ec398134853e0f64ac9:

  blk-mq: fixup type of 'ret' in __blk_mq_try_issue_directly() (2017-06-12 11:22:46 -0600)
