Some platforms may be configured to not support notification events from certain sources. This scenario is already handled gracefully by avoiding any attempt to send a notification enable request for those sources, as such requests would inevitably fail. However, in a more extreme case, a platform might not support even a single source for a given event type. In this situation, allowing notifier registration is meaningless. Attempting to register a notifier would serve no purpose and only result in unnecessary overhead. To address this, we now detect such conditions during the protocol initialization. When identified, we flag the unsupported event types and reject any subsequent notifier registration attempts for them with -ENOTSUPP. This early rejection avoids redundant processing and simplifies runtime logic.

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 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.
