Now that we removed ->iterate we don't need to check for either ->iterate or ->iterate_shared in file_needs_f_pos_lock(). Simply check for ->iterate_shared instead. This will tell us whether we need to unconditionally take the lock. Not just does it allow us to avoid checking f_inode's mode it also actually clearly shows that we're locking because of readdir.

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.
