From a88cc108f6f39e56577793f66ac69eb0e18ae099 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 17 Mar 2014 12:21:54 +0000 Subject: lib: Export interval_tree 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 Signed-off-by: Chris Wilson Cc: Michel Lespinasse Cc: Rik van Riel Cc: Peter Zijlstra Cc: Andrea Arcangeli Cc: David Woodhouse Cc: Andrew Morton Reviewed-by: Michel Lespinasse [Acked for inclusion via drm/i915 by Andrew Morton.] [danvet: switch to _GPL as per the mailing list discussion.] Signed-off-by: Daniel Vetter --- lib/interval_tree.c | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'lib/interval_tree.c') diff --git a/lib/interval_tree.c b/lib/interval_tree.c index e6eb406f2d65..f367f9ad544c 100644 --- a/lib/interval_tree.c +++ b/lib/interval_tree.c @@ -1,6 +1,7 @@ #include #include #include +#include #define START(node) ((node)->start) #define LAST(node) ((node)->last) @@ -8,3 +9,8 @@ INTERVAL_TREE_DEFINE(struct interval_tree_node, rb, unsigned long, __subtree_last, START, LAST,, interval_tree) + +EXPORT_SYMBOL_GPL(interval_tree_insert); +EXPORT_SYMBOL_GPL(interval_tree_remove); +EXPORT_SYMBOL_GPL(interval_tree_iter_first); +EXPORT_SYMBOL_GPL(interval_tree_iter_next); -- cgit v1.2.3
