mainlining shenanigans
Go to file
Linus Torvalds 9bd553929f This has been a large cycle for RDMA, with several major patch series
reworking parts of the core code.
 
 - Rework the so-called 'gid cache' and internal APIs to use a kref'd
   pointer to a struct instead of copying, push this upwards into the
   callers and add more stuff to the struct. The new design avoids some
   ugly races the old one suffered with. This is part of the namespace
   enablement work as the new struct is learning to be namespace aware.
 
 - Various uapi cleanups, moving more stuff to include/uapi and fixing some
   long standing bugs that have recently been discovered.
 
 - Driver updates for mlx5, mlx4 i40iw, rxe, cxgb4, hfi1, usnic, pvrdma,
   and hns
 
 - Provide max_send_sge and max_recv_sge attributes to better support HW
   where these values are asymmetric.
 
 - mlx5 user API 'devx' allows sending commands directly to the device FW,
   instead of trying to cram every wild and niche feature into the common
   API. Sort of like what GPU does.
 
 - Major write() and ioctl() API rework to cleanly support PCI device hot
   unplug and advance the ioctl conversion work
 
 - Sparse and compile warning cleanups
 
 - Add 'const' to the ib_poll_cq() signature, and permit a NULL 'bad_wr',
   which is the common use case
 
 - Various patches to avoid high order allocations across the stack
 
 - SRQ support for cxgb4, hns and qedr
 
 - Changes to IPoIB to better follow the netdev model for working with
   struct net_device liftime

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
