perf: fix duplicate header inclusion ... #include <stdbool.h> somehow got duplicated on its way to linus's tree (probably as a conflict resolution as things got sent through multiple trees) Signed-off-by: Michel Lespinasse <walken@google.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Michel Lespinasse   authored and   Linus Torvalds   commited 2012-10-11 08:50:17 +09:00	ec073619cd
rbtree: adjust node color in __rb_erase_color() only when necessary ... In __rb_erase_color(), we were always setting a node to black after exiting the main loop. And in one case, after fixing up the tree to satisfy all rbtree invariants, we were setting the current node to root just to guarantee a loop exit, at which point the root would be set to black. However this is not necessary, as the root of an rbtree is already known to be black. The only case where the color flip is required is when we exit the loop due to the current node being red, and it's easiest to just do the flip at that point instead of doing it after the loop.

perf_counter tools: Share rbtree.with the kernel ... The tools/perf/util/rbtree.c copy already drifted by three csets: 4b324126e0 4c60117811 16c047add3 So remove the copy and use the lib/rbtree.c directly, sharing the source code while still generating a separate object file, since tools/perf uses a far more agressive -O6 switch.
