FMODE_NOCMTIME used to be just a hack for the legacy XFS handle-based "invisible I/O", but commite5e9b24ab8("nfsd: freeze c/mtime updates with outstanding WRITE_ATTRS delegation") started using it from generic callers. I'm not sure other file systems are actually read for this in general, so the above commit should get a closer look, but for it to make any sense, file_update_time needs to respect the flag. Lift the check from file_modified_flags to file_update_time so that users of file_update_time inherit the behavior and so that all the checks are done in one place.

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 reStructuredText 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.
