We recently moved fsnotify hook, rw_verify_area() and other checks from do_iter_write() out to its two callers. for consistency, do the same thing for do_iter_read() - move the rw_verify_area() checks and fsnotify hook to the callers vfs_iter_read() and vfs_readv(). This aligns those vfs helpers with the pattern used in vfs_read() and vfs_iocb_iter_read() and the vfs write helpers, where all the checks are in the vfs helpers and the do_* or call_* helpers do the work. This is needed for fanotify "pre content" events.

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.
