    lib: Export interval_tree · a88cc108
    Chris Wilson authored
    lib/interval_tree.c provides a simple interface for an interval-tree
    (an augmented red-black tree) but is only built when testing the generic
    macros for building interval-trees. For drivers with modest needs,
    export the simple interval-tree library as is.
    v2: Lots of help from Michel Lespinasse to only compile the code
        as required:
        - make INTERVAL_TREE a config option
        - make INTERVAL_TREE_TEST select the library functions
          and sanitize the filenames & Makefile
        - prepare interval_tree for being built as a module if required
