commitd826e5b827upstream. Ever since the commit0e0cb35b41, it's possible to lose an open stateid while retrying a CLOSE due to ERR_OLD_STATEID. Once that happens, operations that require openstateid fail with EAGAIN which is propagated to the application then tests like generic/446 and generic/168 fail with "Resource temporarily unavailable". Instead of returning this error, initiate state recovery when possible to recover the open stateid and then try calling nfs4_select_rw_stateid() again.

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.
