Currently, instead of performing a short write, iomap_file_buffered_write will fail when part of its iov iterator cannot be read. In contrast, gfs2_file_buffered_write will loop around if it can read part of the iov iterator, so we can end up in an endless loop. This should be fixed in iomap_file_buffered_write (and also generic_perform_write), but this comes a bit late in the 5.16 development cycle, so work around it in the filesystem by trimming the iov iterator to the known-good size for now.

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.
