Transactions to send data for a network device can be allocated at any time up until the point the TX queue is stopped. It is possible for ipa_start_xmit() to be called in one context just before a the transmit queue is stopped in another. Update gsi_channel_trans_last() so that for TX channels the allocated and pending transaction lists are checked--in addition to the completed and polled lists--to determine the "last" transaction. This means any transaction that has been allocated before the TX queue is stopped will be allowed to complete before we conclude the channel is quiesced. Rework the function a bit to use a list pointer and gotos. Signed-off-by: Alex Elder <elder@linaro.org> Acked-by: Willem de Bruijn <willemb@google.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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.
