This patch will add a mutex that a connection can allocate a writequeue entry buffer only at a sleepable context at one time. If multiple caller waits at the writequeue spinlock and the spinlock gets release it could be that multiple new writequeue page buffers were allocated instead of allocate one writequeue page buffer and other waiters will use remaining buffer of it. It will only be the case for sleepable context which is the common case. In non-sleepable contexts like retransmission we just don't care about such behaviour.

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.
