skb_segment by default transfers allocated wmem from the gso skb to the tail of the segment list. This underreports real truesize of the list, especially if the tail might be dropped. Similar to tcp_gso_segment, update wmem_alloc with the aggregate list truesize and make each segment responsible for its own share by setting skb->destructor. Clear gso_skb->destructor prior to calling skb_segment to skip the default assignment to tail. Signed-off-by: Willem de Bruijn <willemb@google.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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
