New APIs are added to support fast update DEKs. As a pool is created for each key purpose (type), one pair of pool APIs to get/put pool. Anotehr pair of DEKs APIs is to get DEK object from pool and update it with user key, or free it back to the pool. As The bulk allocation and destruction will be supported in later patches, old implementation is used here. To support these APIs, pool and dek structs are defined first. Only small number of fields are stored in them. For example, key_purpose and refcnt in pool struct, DEK object id in dek struct. More fields will be added to these structs in later patches, for example, the different bulk lists for pool struct, the bulk pointer dek struct belongs to, and a list_entry for the list in a pool, which is used to save keys waiting for being freed while other thread is doing sync. Besides the creation and destruction interfaces, new one is also added to get obj id. Currently these APIs are planned to used by TLS only.

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.
