We're seeing spurious calls to nfs4_schedule_stateid_recovery() from nfs4_do_open() in situations where there is no trigger coming from the server. In theory the code path being triggered is supposed to notice that state recovery happened while we were processing the open call result from the server, before the open stateid is published. However in the years since that code was added, we've also added the 'session draining' mechanism, which ensures that the state recovery will wait until all the session slots have been returned. In nfs4_do_open() the session slot is only returned on exit of the function, so we don't need the legacy mechanism. Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
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.
