Patch series "Reduce a vmalloc internal lock contention preparation work". This small serias is preparation work to implement per-cpu vmalloc allocation in order to reduce a high internal lock contention. This series does not introduce any functional changes, it is only about preparation. This patch (of 5): Currently link_va() and unlik_va(), in order to figure out a tree type, compares a passed root value with a global free_vmap_area_root variable to distinguish the augmented rb-tree from a regular one. It is hard coded since such functions can manipulate only with specific "free_vmap_area_root" tree that represents a global free vmap space. Make it common by introducing "_augment" versions of both internal functions, so it is possible to deal with different trees. There is no functional change as a result of this patch.

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.
