If the GETATTR request on a file that has write delegation in effect and the request attributes include the change info and size attribute then the write delegation is recalled. If the delegation is returned within 30ms then the GETATTR is serviced as normal otherwise the NFS4ERR_DELAY error is returned for the GETATTR. Add counter for write delegation recall due to conflict GETATTR. This is used to evaluate the need to implement CB_GETATTR to adoid recalling the delegation with conflit GETATTR.

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.
