Convert the ioctl method syscall path to use the uverbs_api data structures. The new uapi structure includes all the same information, just in a different and more optimal way. - Use attr_bkey instead of 2 level radix trees for everything related to attributes. This includes the attribute storage, presence, and detection of missing mandatory attributes. - Avoid iterating over all attribute storage at finish, instead use find_first_bit with the attr_bkey to locate only those attrs that need cleanup. - Organize things to always run, and always rely on, cleanup. This avoids a bunch of tricky error unwind cases. - Locate the method using the radix tree, and locate the attributes using a very efficient incremental radix tree lookup - Use the precomputed destroy_bkey to handle uobject destruction - Use the precomputed allocation sizes and precomputed 'need_stack' to avoid maths in the fast path. This is optimal if userspace does not pass (many) unsupported attributes. Overall this results in much better codegen for the attribute accessors, everything is now stored in bitmaps or linear arrays indexed by attr_bkey. The compiler can compute attr_bkey values at compile time for all method attributes, meaning things like uverbs_attr_is_valid() now compile into single instruction bit tests.

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.
