Linux kernel source tree
e27e43a5cb
The change to allow page_pool to handle its own page destruction instead
of relying on XDP removed the trace_mem_return_failed() tracepoint caller,
but did not remove the mem_return_failed trace event. As trace events take
up memory when they are created regardless of if they are used or not,
having this unused event around wastes around 5K of memory.
Remove the unused event.

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.
