mainlining shenanigans
c9aa889b03
This adds nowait support to the RAID10 driver. Very similar to raid1 driver changes. It makes RAID10 driver return with EAGAIN for situations where it could wait for eg: - Waiting for the barrier, - Reshape operation, - Discard operation. wait_barrier() and regular_request_wait() fn are modified to return bool to support error for wait barriers. They returns true in case of wait or if wait is not required and returns false if wait was required but not performed to support nowait.

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.
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.
