Subject: [PATCH 1/5] radix tree test suite: fix mapshift build target
Date: Thu,  3 May 2018 13:24:26 -0600	[thread overview]
Message-ID: <20180503192430.7582-2-ross.zwisler@linux.intel.com> (raw)
In-Reply-To: <20180503192430.7582-1-ross.zwisler@linux.intel.com>

The following commit

  commit c6ce3e2fe3da ("radix tree test suite: Add config option for map
  shift")

Introduced a phony makefile target called 'mapshift' that ends up
generating the file generated/map-shift.h.  This phony target was then
added as a dependency of the top level 'targets' build target, which is
what is run when you go to tools/testing/radix-tree and just type 'make'.

Unfortunately, this phony target doesn't actually work as a dependency, so
you end up getting:

$ make
make: *** No rule to make target 'generated/map-shift.h', needed by 'main.o'.  Stop.
make: *** Waiting for unfinished jobs....

Fix this by making the file generated/map-shift.h our real makefile target,
and add this a dependency of the top level build target.
