Pull smbdirect updates from Steve French:
 "Move smbdirect server and client code to common directory:

   - temporary use of smbdirect_all_c_files.c to allow micro steps

   - factor out common functions into a smbdirect.ko.

   - convert cifs.ko to use smbdirect.ko

   - convert ksmbd.ko to use smbdirect.ko

   - let smbdirect.ko use global workqueues

   - move ib_client logic from ksmbd.ko into smbdirect.ko

   - remove smbdirect_all_c_files.c hack again

   - some locking and teardown related fixes on top"

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

The Linux kernel is the core of any Linux operating system. It manages hardware,
system resources, and provides the fundamental services for all other software.

Quick Start
-----------

* Report a bug: See Documentation/admin-guide/reporting-issues.rst
* Get the latest kernel: https://kernel.org
* Build the kernel: See Documentation/admin-guide/quickly-build-trimmed-linux.rst
* Join the community: https://lore.kernel.org/

Essential Documentation
-----------------------

All users should be familiar with:

* Building requirements: Documentation/process/changes.rst
* Code of Conduct: Documentation/process/code-of-conduct.rst
* License: See COPYING

Documentation can be built with make htmldocs or viewed online at:
https://www.kernel.org/doc/html/latest/
