mptcp_push_pending() is called even on orphaned msk (and orphaned subflows), if there is outstanding data at close() time. To cope with the above MPTCP needs to handle explicitly the allocation failure on xmit. The newly introduced do_tcp_sendfrag() allows that, just plug it. We can additionally drop a couple of sanity checks, duplicate in the TCP code. Signed-off-by: Paolo Abeni <pabeni@redhat.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.
