This is a prerequisite to allow receiving data from multiple subflows without re-injection. Instead of dropping the OoO - "future" data in subflow_check_data_avail(), call into __mptcp_move_skbs() and let the msk drop that. To avoid code duplication factor out the mptcp_subflow_discard_data() helper. Note that __mptcp_move_skbs() can now find multiple subflows with data avail (comprising to-be-discarded data), so must update the byte counter incrementally. v1 -> v2: - fix checkpatch issues (unsigned -> unsigned int) Signed-off-by: Paolo Abeni <pabeni@redhat.com> Reviewed-by: Mat Martineau <mathew.j.martineau@linux.intel.com> Signed-off-by: David S.

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.
