CIFS uses pre-allocated crypto structures to calculate signatures for both incoming and outgoing packets. In this way it doesn't need to allocate crypto structures for every packet, but it requires a lock to prevent concurrent access to crypto structures. Remove the lock by allocating crypto structures on the fly for incoming packets. At the same time, we can still use pre-allocated crypto structures for outgoing packets, as they are already protected by transport lock srv_mutex.

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.
