[ Upstream commit cdc556600c0133575487cc69fb3128440b3c3e92 ] When vfs_iter_write() starts to fail because a file system is full, a bunch of writes can fail at once with ENOSPC. These writes repeatedly invoke nfsd_reset_boot_verifier() in quick succession. Ensure that the time it grabs doesn't go backwards due to an ntp adjustment going on at the same time.

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.
