Milk-V Jupiter Linux kernel

af_alg_sendmsg() takes data-to-be-copied that's provided by write(),
send(), sendmsg() and similar into pages that it allocates and will merge
new data into the last page in the list, based on the value of ctx->merge.
Now that af_alg_sendmsg() accepts MSG_SPLICE_PAGES, it adds spliced pages
directly into the list and then incorrectly appends data to them if there's
space left because ctx->merge says that it can. This was cleared by
af_alg_sendpage(), but that got lost.
Fix this by skipping the merge if MSG_SPLICE_PAGES is specified and
clearing ctx->merge after MSG_SPLICE_PAGES has added stuff to the list.

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.
