For TX buffers that require an additional async notification via QAOB, the TX completion code can now manage all the necessary processing if the notification has already occurred (or is occurring concurrently). In such cases we can avoid replacing the metadata that is associated with the buffer's slot on the ring, and just keep using the current one. As qeth_clear_output_buffer() will also handle any kmem cache-allocated memory that was mapped into the TX buffer, qeth_qdio_handle_aob() doesn't need to worry about it. While at it, also remove the unneeded forward declaration for qeth_init_qdio_out_buf(). Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
