generic_update_time() always passes I_DIRTY_TIME to __mark_inode_dirty(), which doesn't really make sense because (a) generic_update_time() might be asked to do only an i_version update, not also a timestamps update; and (b) I_DIRTY_TIME is only supposed to be set in i_state if the filesystem has lazytime enabled, so using it unconditionally in generic_update_time() is inconsistent. As a result there is a weird edge case where if only an i_version update was requested (not also a timestamps update) but it is no longer needed (i.e. inode_maybe_inc_iversion() returns false), then I_DIRTY_TIME will be set in i_state even if the filesystem isn't mounted with lazytime. Fix this by only passing I_DIRTY_TIME to __mark_inode_dirty() if the timestamps were updated and the filesystem has lazytime enabled.

README
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.
