commit 88010155f02b2c3b03c71609ba6ceeb457ece095 upstream.
Fix the cifs filesystem implementations of FALLOC_FL_INSERT_RANGE, in
smb3_insert_range(), to set i_size after extending the file on the server
and before we do the copy to open the gap (as we don't clean up the EOF
marker if the copy fails).
Fixes: 7fe6fe95b936 ("cifs: add FALLOC_FL_INSERT_RANGE support")

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.
